Something a gay guy says when hes up-set or scared/shocked. he says it with a lisp because for some reason all gay ppl have one. so the S becomes a TH. You may have heard the character Mr. Slave from Southpark say it.
mr slave: did you guyth here that geroge michael ith coming to town?
some gay friend: oh yeth, oh yeth
mr slave: oh jeethuth chrithe, oh jeethuth chrithe!
