Boke and Tsukkomi
Manzai (two-person stand-up comedy) in the Kansai area typically has one person play the “boke” and the other the “tsukkomi.”
The boke makes people laugh by saying funny things, acting weird, or reacting weirdly to what the tsukkomi says. The tsukkomi then cuts in, pointing out the weirdity. What the tsukkomi says then is supposed to be the punch line, getting bigger laughs. The tsukkomi can be physical as well as verbal, with the tsukkomi slapping the boke’s chest, for example.
The boke is in charge of keeping things going in the routines. By having the tsukkomi cut in, the tsukkomi works to end a topic (or subtopic), and give the routine structure a good rhythm.
