I've heard a lot of different phrases for ballbusting, like "a kick in the nuts" or "groin attack" or "punch in the goolies" or "right in the sack" or "kick where the sun don't shine" etc., along with some more interesting, sexy ones like "I'll grab your manhood" or "scramble your eggs" or "I once went to the Nutcracker Suite," or my personal favorite "today I'll be eating crushed eggs!" Have any of you heard any similar phrases referring to ballbusting?
