From the trope page itself:
Also commonly known in comics fandoms as "Fight Then Team Up," or the "Marvel Misunderstanding" (even in the Marvel Bullpen!)
The phrase probably first comes from the 1930s Popeye comic strip as a catchphrase of Wimpy, who often gets Popeye to fight big tough guys he's wronged - thus becoming a Got Volunteered
situation. "Let's You and Him Fight" is also the title of a Fleischer Studios Popeye short revolving around a boxing match between Popeye and Bluto. It also appears in Eric Berne's 1964 book Games People Play as one of the identified behavior patterns, although he used it to describe what we call Triang Relations.
the current name sounds like dialogue and comes from an obscure reference that only tangentially fits the description.
The laconic is "Heroes fighting heroes due to confusion, egos or some other factor" and is usually used for two heroes fighting each other when they first meet in a crossover.
The name, as per the description given, comes from either a sidekick tricking the hero into fighting a third party for him (Wimpy explanation which is better as Got Volunteered
) or a hero vs a villain (Popeye vs Bluto) or as another name for Triang Relations
Seeing as the trope page itself spells out how its a terrible name and suggests better ones, can we change to one of the better ones so its easier to find?
