A Cup?
A cup can do more harm than good... My friend took it in the goolies first time he came. So next time he wore his tai kwondo cup, brilliant solution. He hadn't worn it in ages.
It came time to play.
It didn't fit he told me.
He wore it anyway.
We walked, ran and got killed in the most painful ways.
If you wear one those who have never done or had a friend they better fit and be warned that it will kill if you run.
Or so my friend said.
