Something exclusive to call of duty and gmod, where you press Y at a certain point in an animation and it changes weapon instantly, it can be done with many different things and requires very fast timing to get them consistently. Unless it is a Moni NAC.

Nac Swap
Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
Beavis: Um, okay. (heh heh heh heh).
