glorified, formal name for any trailer trash hussy, skanky crack whore or downwardly mobile street prostitute who feigns class, taste and style despite appearances to the contrary.
"An upper-class woman making her first appearance into fashionable society". It's a full-time job for a debutante to convince her parents she's as pure as royalty and chaste as a saint. In reality, everyone knows all the debs do is get fabulously drunk after!
