I'm thinking underwear juice isn't exactly a myth. But, you know...I must admit there is a name I've been dying to use.
My 1st cousin is married to a cool gal from Honduras and there is a term that describes a guy under a spell of a woman. I can't remember the actual term but said woman is believed to have "underwear juice" which keeps her man in line.
I'd like to use that name for something........
