When you pick me up on Friday, are you gonna bring me anything?
Oh, don't worry Dad, you know, it don't matter what we do
Cause I don't call him daddy, he can never be like you."
A character is taken in by a Parental Substitute of some sort, usually of a more permanent variety such as an official foster parent or step parent, and they're considering calling them "mom" or "dad" despite the lack of biological connection. Agreeing to call them "mom" or "dad" will lead to a perceived level of closeness than simply calling them by their first name, but also may lead to the protagonist feeling like they're shunning their birth parents, who are definitely not the person raising them. It typically causes the protagonist tons of angst and is a handy device for exploring the familial dynamics between the characters.
- One of the character in Death Parade regrets that he refused to refer to his step-mother as "mom" when he was alive.
- In Magi: The Labyrinth of Magic, Alibaba seems to have never quite come to terms with meeting his birth father; even when he gets a vision of his dead parents, he starts to say "Father" but then switches to "Previous King of Balbadd."
- According to supplementary material in Lyrical Nanoha, it took a while before Fate could comfortably call Lindy "mother" instead of just "Lindy".

- Fanfictions for My Little Pony: Friendship Is Magic:
- Fanfic sometimes take on the issue of how Twilight and Spike view each other. It is a sort of Parent/Sibling/Assistant relation. Official material seems to have settled on "Assistant" and he calls her "Twilight" in-show, though several episodes show that Twilight is the closest thing to a mother that he has. In fanfic just about anything goes.
- Twilight was mentored by princess Celestia during her youth. As such it is a common topic to explore just what their relation is. Mentor/student? Second mother figure? Princess/Subject? Friend? That Twilight herself got a promotion to princess doesn't make things easier.
- A few fanfictions featuring Rainbow Dash adopting Scootaloo have brought up this question. Though often there Scoots sticks with calling Rainbow Dash by name.
- In secooper87's Adventures of a Line Hopper series The alternate timeline daughter of the Doctor and Buffy Summers calls the Doctor her "father" as, biologically that's what he is to her, but calls the inter-dimensional being that raised her "Dad" and is very adamant the two terms are not interchangeable. After she begins to be raised by the main-universe Buffy, she calls her "Mom" although had to remind herself to call her that for sometime. A lot of times she'll start to call out for "Buf-I mean-Mom"
- In the Emergency! fic Lost and Found, Roy and Joanne are mama and papa to John's infant daughter Melissa, intending to adopt her after John is abducted and feared dead and her mother doesn't want her.

In the sequel, "Reclamation," a psychiatrist tells the couple to find a new designation as John takes his place as the baby's father. The Honorary Uncle thing doesn't work, though, and they end up remaining Mama Joanne and Papa Roy.
- In a now-deleted The Amazing Chan and the Chan Clan / Winx Club crossover fic, Anne Chan was so close to her deceased mother that she refuses to call her stepmother her mother and even screams at Layla for accidentally referring to her as such. In the previous crossover, a sign that Alan was under the enemy's control was him accidentally saying "mom" instead of his stepmother's first name. (Though another Chan Clan fic also explains that Scooter and Mimi are the only ones who call her "mom" due to the rest being old enough to remember their birth mother.)
- In I'm a Marvel... and I'm a DC, Harley Quinn hooks up with the Green Goblin and moves into his house, and Harry has this forced on him.

Harry: You're not even married!
- In the Dusk to Dawn series, Damian Wayne has a less tumultuous case of this with Selina Kyle. Their relationship has a (one-sided) rocky start, but they reach a friendly First-Name Basis at the end of the first book, and she grows as his resident maternal figure throughout the following two. When Selina and Bruce are finally married, Damian is ready to call her "Mom" by the wedding's reception. This contrasts how Damian refers to his birth mother Talia with a respectful but formal "Mother," except when she becomes a Broken Pedestal, then he coldly calls her "Talia."
- While not a problem in the canon, it's a fairly popular story device in the Phineas and Ferb fanwork community that Candace originally refused to recognize Laurence as her dad at the beginning of their relationship before moving into the Daddy's Girl relationship she has with him in present day.
- In Live a Hero, Inko wishes that her adoptive son Izuku would call her "Mom" instead of "Inko-san", though she still considers it a step above the even more formal "Midoriya-san" they started with. Considering that his biological parents left him and his sister for dead and allowed them to get scooped up by the League of Villains to be turned into Tykebombs, it's easy to see why this is the case. Despite this, the narration makes it adamantly clear that Izuku thinks of her as his mom and loves her just as much as his canon counterpart, if not even more so.
- In adel aka's video about rewriting Yang in RWBY, he gave her this problem as a driving element of her character. Yang's biological mother Raven walked out when she was a baby, with Yang's step-mother Summer being the only mother she's ever known. When Yang was very young, Summer died. Yang has always been curious about Raven but her father refuses to tell her. Eventually, he promises to tell her if she becomes a huntress. Throughout her life Yang has felt uncomfortable calling Summer her mother, which upsets her half-sister Ruby. Yang comes to terms with Summer as her mother after seeing a heartfelt video that Summer made for her. Upon meeting her cold biological mother Raven, Yang disowns her by stating that her mother is Summer.

He uses a string of "Dad" words that Batman continually rebuffs, but eventually allows "Padre," since it can also mean "buddy." (Presumably he's mixing it up with "compadre.") Of course, near the end:
Batman: Don't call me "Padre." Call me...(Dramatic Unmask) "Dads."
- In When Marnie Was There, Anna calls her foster mother "auntie". She began addressing her this way due to a belief that her mother was simply using her for money. Towards the end she addresses her as "mother" after realizing that her family doesn't take care of her just for the foster care money.
- In The Sand Lot main character Scotty's mother had just married a new man he doesn't connect with off the bat. After gaining new friends and learning about baseball, he begins to find some more common ground with him and says in the closing narration he soon had no problem calling him "dad".
- Step Brothers plays this for laughs.
Brennan: I'm not gonna call him Dad.
Nancy: Brennan, you're 39 years old. I wouldn't expect you to call him Dad.
Brennan: Well I'm not going to, ever! Even if there's a fire!
- Shaun of the Dead has the recurring line, "He's not my dad, he's my stepdad" from Shaun about his stepfather Phillip. It stems from Shaun viewing Phillip as a Jerkass, rather than the Jerk with a Heart of Gold he is. Before turning into a zombie Phillip tells Shaun he's always loved him and Shaun finally acknowledges Phillip as his dad.

Sanya runs after the prison van, saying "Daddy! Don't leave us!" The voiceover reflects that after that, Sanya never saw the vision of his real father again, because he had "betrayed him."
- In Boy, the title character initially addresses his estranged father Alamein as "Dad," but Alamein asks his not too, saying that it feels weird. Instead he suggests that Boy call him "Shogun." (Alamein may be a deadbeat and an aspiring gang leader, but he is also a massive dork.)
- In The Life Aquatic with Steve Zissou, the fact that the title character doesn't want his presumptive son to call him this is a sign of his immaturity.
Ned: I can't believe I asked if I could call you "Dad." Of course you said no.Steve: I let you call me "Stevesie." It sounds better.Ned: It doesn't mean the same thing.
- In Bill & Ted's Excellent Adventure, Bill actually seems to think that he has to call Missy "Mom," despite the fact that she's about three years older than him.

Dee Dee, who helped raise the Harrigan kids as their housekeeper for years before she married their father, is unfazed by this, knowing how much their mother meant to the family.

Oddly enough, her brother Charles Wallace calls her that too, but after some Time Traveling adventures switches to her childhood nickname, Beezie.
- The Brady Bunch: Greg, Peter and Bobby call their stepmother, Carol, "Mom" immediately; likewise with Marcia, Jan and Cindy, they address stepfather Mike as "Dad." (Indeed, the concept of stepmother and stepfather was downplayed, only referred to in a couple of episodes during the first season, and by the end of that first season, it's as though they had always known Mike and Carol as "Mom" and "Dad.")
- The Sarah Jane Adventures:
- Luke is very quick to call Sarah Jane "Mum", but she asks him not to because she's new to the whole parenting thing and isn't quite ready for that level of closeness. They get over it by the end of the second serial and she's "Mum" to Luke for the rest of the series.
- Luke's Suspiciously Similar Substitute/adopted sister Sky on the other hand, calls Sarah Jane by her first name. The series was canceled due to the untimely death of the lead actress before it could be further explored as to why.
- In the serial "The Wedding of Sarah Jane Smith", before Luke meets Peter Dalton (Sarah Jane's boyfriend) for the first time, he wonders if he is going to call Peter "dad". We never see what he decides to call Peter, due to the wedding's... interruption... at the hands of the Tenth Doctor, and Peter's subsequent death.
- Strangely averted in The Good Place. After Jason marries Janet, he has no problem referring to Michael as "Dad", despite the fact that a) Michael is opposed to the marriage due to Janet having been made to essentially be Siri in human form, and b) he is not Janet's father, as she has no parents.
- Diff'rent Strokes: When Willis and Arnold start living with the man who eventually adopts them, they call him Mr. Drummond. They eventually ask his permission to call him Dad, which he gives (even before he officially adopts them). The explicitly do not call him Papa, which was their name for their biological father.
- Later in the series, when Drummond remarries, Arnold and Willis (and Kimberly, too) refer to Maggie by her given name, even though she is their stepmother. (The only one that gets the term "mama" is Arnold and Willis' biological mother.) Maggie's son, Sam, always addresses Drummond as "Mr. D," even though he is now his stepfather.

- Averted in ''Sons of Anarchy". When we meet Jax and Clay, it is clear that Clay has been married to Jax's mother, Gemma, for many years. However, despite the fact that Clay often calls Jax "son", Jax always refers to Clay by his name. It's possibly due to the fact that by the series' timeline of when JT, Jax's biological father, died, Jax was already a teenager and had known Clay for years as JT's best friend. Later, when Jax and Clay are more often at cross purposes, Jax begins to correct people when they refer to Clay as his father and he explicitly tells Clay to stop calling him "son."

Cause I don't call him daddy, he can never be like you.
- In Teen Girl Squad, So-and-So once refers to her stepmother as "Judith" in a very sneering tone.
- A retroactive version of this occurs with Yang in RWBY. Yang's biological mother Raven ran off when she was a baby, leaving her step-mother Summer as the only mom she's ever known. She didn't know that Ruby wasn't her full sister until after Summer had died. When talking to Blake about her in Volume 2, she refers to Summer as "our mom". But by Volume 5, she's reverted to exclusively calling Summer "Ruby's mom" and refers to Raven as her mother.

- In The Dragon Prince, it's clear that Callum and his stepfather, King Harrow, think of each other as family, but neither seems quite able to spit it out, and Callum addresses him as "My King" or "the King," which his stepbrother Ezran even comments on. He actually does call out "Dad!" just before Harrow is murdered.
