Means when, you say a joke so funny that even you have to laugh, even if you are the only one. Though it's kinda lame laughing with yourself, but, you just cant help yourself :)
haha, knock knock, whos there? boo..boo who?
ohh dont cry its only a joke...HAHAHA
When a woman is giving felatio and has both hands on the shaft and twists them in oppisite directions while simutaneously moving them up and down. Just like using a fresh pepper grinder.
Wow!!! Look at the way she is crackin the pepper while giving me head.
