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. This can also sometimes happen with estranged biological parents who have recently re-entered their kid's life.
- A funny example in a Progressive commercial; a single mother introduces Jamie to her sons, saying he'd be helping out from now on. She meant as an insurance agent, but they get the wrong idea and one of them says he's not calling Jamie dad.

- A heart-breaking example in Monster; a One-Shot Character who married a widow was struggling for his stepson to accept him as a father. In the episode, the stepson finally called him dad for the first time as he was leaving for work. Unfortunately, he ended up being Johan's latest victim.

- 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 she had to remind herself to call her that for some time. A lot of times she'll start to call out for "Buf-I mean-Mom"

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.

- 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.

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.
- In Turning Tables, when Pepper adopts Peter, he is upfront about how he does not intend on calling her "mom". She respects that as long as he acknowledges that she is his guardian.

As they grow closer, Peter starts to address her as "mom", if not as a habit.
- Discussed early on in the Dangerverse, where the Pack-adults come to the conclusion that, since they are not the biological parents of their "cubs", encouraging the cubs to address them as "Mom" and "Dad" wouldn't really be appropriate. Instead, the cubs simply refer to the pack-parents (who they love very much) by their first names or assorted nicknames. The one exception is Meghan, who calls Sirius and Aletha "Dadfoot" and "Mamaletha" because they are her biological parents.
- Later on in the story, Remus uses a blood magic ritual to make Harry his biological son. As soon as the ritual is complete, Harry pointedly addresses Remus as "Dad". Cue Manly Tears.

- Implied in Up. When Russell mentions how Phyllis told him to stop calling his dad, Carl asks why he calls his mother by her name, to which Russell confusedly replies that Phyllis isn't his mother. Carl quickly works it out in his head and shuts up about it.
- In The LEGO Batman Movie, Bruce Wayne accidentally adopts Dick Grayson, with Batman sharing custody as his co-dad. (Yeah, Dick actually bought this.) 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.

- Shaun of the Dead has the recurring line, "He's not my dad, he's my stepdad" from Shaun about his stepfather Phillip.

- 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.

- Natalie's children in Catherine Anderson's Bright Eyes are officially adopted by Zeke Coulter and have no problem seeing him as "dad" due to their biological father not having been the best guy around.

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.
- At the end of The Ballad of Songbirds and Snakes, Coriolanus Snow isn't sure what to call Strabo Plinth. "Father" doesn't feel right since Plinth couldn't legally adopt him because he's 18 and therefore made him his heir instead. He ends up calling him "sir" a lot.
- 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."

- Drake & Josh: During the first couple seasons, Drake and Megan call their stepdad, Walter, "Dad"; while Josh addresses his stepmother, Audrey, as "Mom". Later during the show's run, Drake and Megan start addressing Walter by his first name, to which a confused Walter asks when they started doing that.
- 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".

- 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.
- All in the Family: We never see a flashback episode about how they arrive at this, but Mike calls his mother-in-law "Ma" (as does his wife/her daughter) while he usually calls his father-in-law by his given name, though there was one episode in which they were drunk he addressed Archie as "Dad", with no repercussions.

It doesn't really matter since it turns out they're disinclined to like her no matter what she tries.

- 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."
