Are you fucking kidding, Madoff, Jr?
Aside, a little linguistics observation. While the use of the word "enema" should be a stronger insult based on the idea of the anus, the word "douche" or "douche-bag" is much more pleasurable to use to refer to an unpleasant or disliked person.
Listen to these sentences:
"That guy is a fucking douche"
"That guy is a fucking enema"
I believe this is rooted in the actual sound of the word douche, ˈdüsh, a one syllable word with an "sh," as opposed to a 3 syllable word, ˈe-nə-mə, with 2 "eh"s. Certainly I am conscious of the misogyny within the construction of English, both formal and colloquial, but I really side with the poetry vs. the ideology on this. It's a tough call but "douche" wins out, particularly with a Philadelphia accent.
