Huckle Buck?

My friend recently asked me what huckle buck means so I looked it up:

Huckle buck when you A. Put a girls legs behind her head or B. When you stick your dick in a persons mouth when they least expect it.

So my friend is like how do you stick your dick ones mouth when they least expect it.

I say at a party a girl is a little drunk and talking most likely about herself getting a little loud and you come up behind them shot Their name and popporoni you got dickinyourmouth stew
