Top Definition
Banana Poo is the offspring of two of the foulest existences on the known planet Earth. It consists of foul carbon, and foul sulfur, and more foul, foul stuff. Banana Poo is used to describe anything or anyone that is unpleasant to behold or observe with the senses. It can be used as a synonym for one that is: ugly, fat, stupid, selfish, evil, short, dirty, perverted, pimple-filled, disgusting, untruthful, lazy or cheating, (though only in bad ways--e.g. if one is short but pleasant, "banana poo" should NOT be used) or any combination of the above. Basically, anything that is bad can be referred to as Banana Poo, but on different degrees. Degrees range from the basic Banana Fart to the horrendous Banana Diarrhea.

*Caution* Do NOT attempt to use the term Banana Poo. and. Ryu Poo/Joyce Poo. in the same sentence. It would bring you bad luck (or at least bad breath) for a million millennia.
C: Poomy is such a b*ch, she totally ruined my chances on purpose. She is so fat and ugly and stupid.
T: You mean she is banana poo.

C: Wilema is sooo not who I thought she was. I thought she was nice. What a banana poo.
