pobblebonk
Also known as "the nipple game" but has been extended to allow for testes. Played in a group, each member is tasked with randomly allowing a nipple or testicle to slip out during conversation. Anyone who sees the stray nip or ball must quietly put their finger on their nose. The last to notice and touch their nose must take a shot of tequila.
We played pobblebonk at Amanda's house last weekend. Rob had to do about 20 slammers because Adrian kept getting his nut out and Rob just didn't see it soon enough.
