jillin it 

Much like killin' it, but do not be confused this is NOT your average typo.

Jill is a name given to a drunken friend, who is usually named Julia or any other "J" name, who just does some crazy shit for the joy of others.

Jill on, party people. Jill on.

Sometimes used because "Jill" is just too drunk to type "killin' it."

"She's running around with her butt showing! Totally jillin' it"

"The new Miley Cyrus is jillin' it"

A Jillin' it text: "headde to thf nexr prtu don't eorry I'm still jillin it." Or any other drunk nonsense
