skin-ripping boner
a term used to describe when a person gets such an intense boner that the "inner boner" threatens to part the seams of your "outer boner" like a cartoon chimp squeezing a banana at the base so that it peels, and the "inner banana" flies across the room leaving only the flaccid "outer banana" peel hanging grotesquely over your balls like a popped balloon.
