What a great word! I bet you could get away with using this to describe someone, sounding like  praise, whilst actually slagging them off to those in the know, along the lines of "there we are then" - twat. 

It's bizarre that latin for sex worker sounds so worthy.

Another little gem is Myrmidon, it lives in your imagination as one of these guys, Achilles's posse, but now used as any kind of follower.

The English language and its etymologies never ceases to amaze. I wonder if this is the case in other languages?
