the excrutiating pain a man receives when his balls swell to the size of coconuts because of lack of sex, unfinished bjs, and just not cummin when he knows he should.
Cure: JUST WACK IT MAN!! or get your woman to help you out and do the job right. It's that simple to make the horrible pain go away.
note to all women,
NEVER NEVER NEVER give your man blue balls...its the worse pain he will ever feel in his life and he never deserves it...well, almost never...
