The heroes entered the classical old pub. A particularly nasty guy taunts one of the characters and tries to hit him. The hero dodge and the other guy hits a bigger, nastier guy who proceed to toss him against a table, causing the people sat at that table to react and soon enough three quarters of the customers are tangled in a chaotic battle, launching tables and resorting to dirty fights. You get the picture.

This trope tends to be quite common and is often paired with BarBrawl with some exceptions. The focus point is that it starts as a duel and ends up growing and dragging along other characters, like an avalanche. In westerns this tends to be quite common.

See also BarBrawl, FoodFight, DinerBrawl and EveryoneJoinTheParty. Don't confuse with EscalatingWar.

** In the town of Borracho, a fight between The Great Leslie and Texas Jack quickly turns into an all-out BarBrawl.
** The pie fight scene in develops this way; people walk in to the bakery, see what's going on, get hit by a missile intended for someone else and join the scrum--except, of course, for The Great Leslie, who walks through the crossfire unscathed until someone gets him in the face at close quarters. Obviously, this is PlayedForLaughs.

* ''Any'' FlameWar almost by definition, especially once it reaches InternetBackdraft levels. True, a FlameWar can stay contained between two combatants, but it rarely, if ever, ''does'' and almost always instead drags in anyone who sees it - which is why they tend to be so destructive to anywhere they start.
