Boo Yakacha

A greeting used in place of more boring words such as "hello" or "hi".

It is also something said to make awkward moments lolful.

This word was first used by T-Bone. Although many others have attempted to disprove this and tried to destroy this claim (namely Teegz).

"Boo yakacha. How be you? Lovely weather? Damn straight."

Boo-Yah

A sexual maneuver involving the simultaneous insertion of a man's penis into a woman's vagina and his testicles into her anus. Once this is accomplished, there is nothing left to the maneuver but for the man to remove himself from both orifices whilst exclaiming "Boo-yah!"

Oh yeah, I boo-yah'd that Sandy chick. She knew enough to ask for it by name, too.
