The male equivalent of a Bonerkill; a male who causes the complete and utter eradication of any positive sexual feelings in a woman's
vagina, causing the inside of the
vagina to become drier, or in extreme cases, become on
par with a desert in terms of (lack of) humidity.
"Hey, you hear about that new
guy?"
"Yeah, I've
seen him before, I wouldn't touch him with a ten-foot pole, he's a total
vagina desertificationifier.
