Moldy Muff Syndrome
When a man is able to detect the presence of a woman before she is seen. Due to her nasty twat which often looks like a bulldog eating mayonaise, but not mayonaise like Hellman's more like mayonaise that you left on the picnic table in the sun for two days in July. Side-effects include upset stomach, vomitting, diarrhea, burning eyes, and the tendency to stab yourself in the face with a spork.
