I am particularly fond of faggot, as we are all well acquainted with now, but that is more a blatant pejorative than an actual euphemism.

There are others such as fairy that I've become quite fond but cannot use as I am not of the femme, feminine, or delicate sort; 'fruit cake' has been ruined for me by my homophobic father who used it for homosexuals as much as he used it for "odd people" and those he thought were mentally unwell; but 'daffy', 'pansy', and 'flower' all make me smile despite their tainted use.

I am still a fan of 'faun' being used in some alternative universe for playful, submissive gay boys, and honestly? I wouldn't mind 'cock jockey' coming back in fashion, as vulgar as it is.
