An emoticon that resembles a penis, but has a three at the end. More potent and deadly than your garden-variety penis.

Hmm. That's quite a threenis.

treenis 

Huge penis that can be mistaken for a tree, the kind of thing you see in modern porn. A penis so big you wonder how any mortal woman can take it.

Holy shit! That thing is huge! If your girl can take a treenis like that, she's ruined forever.

treenis 

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!
