Cuttlefish
I don't really like the word "cuddle." I don't mind the actual cuddling, I just don't like the word. (say it out loud...it's just weird...) I think I don't like that word because it makes me think of a cuttlefish. Not that I'm really familiar with the cuttlefish, and I really shouldn't care one way or the other, yet somehow the cuttlefish disgusts me. Anyway, the problem I find is that cuddle doesn't have a synonym that I can think of. You would have to use a whole descriptive phrase, at which point whomever you are talking to would probably reply, "oh, so you were cuddling!'
