Buzzkilling a Buzzkill 

There are 3 ways to do this:
1. say BK instead of buzzkill
2. if someone pinches their nose when someone makes a buzzkill you pinch your face or something else instead
3. make buzzkill sound different and weird like in an accent or something.

Guy1: YOUR MOM!
Guy2: BK! (while pinching chin)
Guy3: you 2 are such boozkialls
Guy4: all 3 of you shutup, you guys are buzzkilling a buzzkill.
