For some reason I really enjoy the word "exquisite" other favorites words are
Nefarious
Sollipsistic
Delinquent
And a compound word in my native language "horfittjävel", I can't translate it here since it would probably get me a severe warning. Let's just say saying it to someone is equating him to a damned [really bad word for the female anatomy] belonging to a lady of the night.
An interresting thing about languages of germanic and mixed slavic/germanic origins is the possibility to combine words in to new words of their own, makes for some really creative cursing...
