- Veronica and her dad in Heathers.
- The two main characters from Planes, Trains and Automobiles, who form an Odd Couple.
- In Guardians of the Galaxy, this Trope could describe the relationship between pretty much any two members of the team (except Groot, who's friendly to everyone), but especially between to Drax and Gamora. In one scene, the former calls the latter a whore and then a few minutes later shoots Nebula with a rocket launcher when she is talking trash to Gamora and planning to attack her.
Drax: No one talks to my friends like that.
- Grumpy Old Men is based on a variant of this trope.
- Gran Torino has Walt and his friend the barber.
- Kiss Kiss Bang Bang has Harry and Perry. Harry is sure that Perry is really his friend, and somehow ends up being right. Harry would give as good as he gets, except he's a colossal ditz and no-one can out-insult Gay Perry anyway.
- The Boys in the Band. Michael and Harold. While it isn't clear they are best friends, two moments reveal their deep relationship: Michael's gift to Harold, and Harold's quiet assurance after giving him a "The Reason You Suck" Speech "I'll call you tomorrow."

- Anakin Skywalker and Obi-Wan Kenobi in the movies and the expanded universe and Legends (Clone Wars and The Clone Wars) but not so much after the former's Face–Heel Turn. At least they become friends again near the end of Return of the Jedi.
- Luke's relationship to Han Solo. Especially when they're arguing over Leia.
- R2-D2 and C-3PO qualify as well.
- In The Lord of the Rings trilogy, Legolas and Gimli are portrayed in this manner. Basically Legolas is Bugs Bunny and Gimli is Daffy Duck. As much as Gimli was exasperated by Legolas and as often as Legolas would act smarmy towards Gimli, the two always ended up being there for each other. This is an exaggeration of a similar relationship in the books.
Gimli: "Never thought I'd die fighting side by side with an Elf."
Legolas: "What about side by side with a friend?"
Gimli: "Aye. I could do that."
- Sam French and Jake Wyer in 50/50 have this in spades, although Jake likes to pretend he can't stand Sam.
- Dante and Randall from Clerks.. They both argue about things all the time and snark at each other (especially Randall, who seems to enjoy messing with Dante), but when it's all said and done, the two are almost inseparable buddies.

- Jorge the conquistador Sanchez member and Carmelo the native Mesoamerican Sanchez member from The Book of Life, have a rather complicated relationship with each other. The former often calling the latter savage and the latter unintentionally bumps around the former. Not surprising considering the complicated history between the conquistadors and Mesoamericans. They're still family though.
- In Teenage Mutant Ninja Turtles (2014), Raphael is constantly at odds with Leonardo, hates being told what to do, and mentions that he's leaving the group the first chance he gets. However at the end, he defers to Leo's leadership and tells the others to do the same, as well as confessing that he says he's leaving because he's really just scared that he's not as good as them, and he only says that to make them bond harder when it feels like things are driving them apart.
- Bond and Q from the James Bond series.
- Michael Patrick Donovan and Thomas Aloysius Gilhoolie from Donovan's Reef: World War II buddies who share the same birthday and make sure they get together every year to punch the crap out of each other.
- Sherlock Holmes and John Watson. Watson always remarks Holmes is too much for him to handle and constantly tries to get out of joining him on his various jaunts, yet invariably they end up working together because Watson likes the chase almost as much as Holmes and they are in sync during investigations, whether or not he wants to accept it.
- It's implied that Nick and Finnick's relationship in Zootopia is pretty much this as they are business partners...who constantly tease, insult, and even threaten each other. However, Finnick did help Judy find Nick near the end, which also implies, as much as he threatens him or laughs at him, he does somewhat care about him.
