slimy samoan
After coming to orgasm from fellatio, sometimes with a mouthful of sperm, the one performing fellatio will sneeze. The mixture of snot and sperm on your penis is known as 'A Slimy Samoan'.
I had never heard of a Slimy Samoan until April had that cold last week. I looked it up on Urban Dictionary, and sure enough, it's called a Slimy Samoan.
