Ninja whinger

Someone that complains by stealth in order to undermine their victims.
A person that uses something you've told them in confidence to get at you behind your back.
Someone that deliberately puts shit on you for personal gain.

Heads up man, that mofo is a ninja whinger - don't tell him shit.

Tongue Ninja

A tongue ninja is like a thumb war, except you have the war in each others mouths. It is kind of like a french kiss, but more violent. The tongue ninja is over once a winner is declared or by forfeit.

"Crazy bitch tried to cut my dick off after I tried to tongue ninja Brad."
