Similar to a "Goose Egg", which occurs when a person is
hit in the
head and a swollen lump appears. The one difference is that this Goose Egg occurs in the genital area rather than the
head, forehead, etc.
Person 1:
Dude I just got done filming my own Jackass show to put on youtube
Person 2: Really? How'd it go?

hit in the balls with a teeter-totter. Now I have dick knuckles, great.
Person 2: Wtf is a dick knuckle?
