dirty rhiannon

A sexual fetish where the woman repeatedly punches the man in the dick while Smash Mouth's "All-Star" plays in the background.

When a woman wears the same thong for a month straight while never showering. Then she takes her thong and makes her lover wear it like a lvl 10 crusty helm of destruction with the ability to keep STDs away simply by scaring them away from the overwhelming stench.
Used in some developing countries as a defense against Mormon Missionaries.
