dusty towel
When a person is performing the act of masterbation and at the peak of climax grabs an old "Dusty towel" and rubs it on his face in an attempt to sneeze. Which in turn will create 9/8 of an orgasm since a human sneeze is said to be the equivalent of 1/8th of an orgasm.
"Hey Jeremy I tottally gave myself a dusty towel last night." "What the fuck is wrong with you Ryan?"
