Jaw Breaker
When you say something to someone, and they repeat the same thing back with a question mark after it, forcing you to answer "yes". Somewhat related to killers.
Wow! That cadet from the second squadron has a real jaw-breaker -- I could only lick his cum-slit because I couldn't even get his throbbing knob in my mouth!

Mandingo Jaw Breaker
Massive cigar. Usually bigger than a massive BBC (Big Black Cock). The term originated in a Youtube video I just watched about rolling cigars, where the man calls big cigars "Mandingo Jaw Breakers".
