Jill On

This is the opposite of the male "jacking off", a girl masturbating can be referred to as Jilling On.

Jon: "Dude I just caught some girl jilling on in the bathroom!"
Brian:"Wow I love co-ed bathrooms!"
Robcat:"Did she really Jill On? thats hilarious!"

jill

the "girl" a guy is taking home to have sex with.

this girl is really his hand, that he is going home to masterbate with. hold it up and the fingers spell out J-i-l-l.

makes him sound cool, even though everyone knows he's pathetic and can't get any.

guy1: "me and my girl had so much sex last night"
guy2: "yeah me too, i met this fucking hot chick named Jill."

1. IDK, my BFF?
2. One who is constantly being sent text messages by 12-year-olds.

"Who could you be texting that much?"
"IDK, my BFF Jill?"
