Ok this is one my friends made up. A treenis is a drawing of a penis with leaves at the top so fags and parents won't think that it's a penis, instead they think it's a tree!
Guy one: (drawing a penis on my friends shirt) LOOK A PENIS!
My friend: MY MOM'LL KILL ME IF SHE SEES THAT! i won't be able to wear that shirt!
Guy 1: No problem! (draws leaves at the top to make it look like a coconut tree) IT'S A TREENIS!
