botty-bot
n.—Gloss: the rear end or derrière. «If I’m going to wear pants, I’m going to wear something that actually contains my entire botty-bot—instead of just hanging around the middle area, scantily, supposedly sexily, like a gift ribbon on a slightly battered parcel.» —“Coming to a bottom near you: pantorexia” by Caitlin Moran Times (London, United Kingdom) Jan. 7, 2008.
