A creature that claims to be female, but appears to have male genitalia. "She" speaks in a low voice, is constantly surrounded by a hoard of pimply lesbians. "She"/It has been know to bust into houses at night and a**-raping anyone it sees. The only known protection is from a hot girl.
Looking at her for too long (in males) will result in what is known as the phenomenon of a "reverse-boner", when the penis turns inside out and slowly turns into a vagina to be raped by the Man-Hands.
The only know cure for a reverse-boner is to look at some hot girl (or p0rn) and get a regular boner.
Spencer: "Did you know it's national Man-hands awareness week?"
Connor: "No I didn't. I better go download some p0rn"
Jamie: "Ah-h-h-h-h-h!!! I got a reverse boner!"
Andrew: "Look, there goes several hot girls down the hallway, coming out from lunch. FOLLOW THEM."
