j-hat on da bozak
A shout from a grown-up telling a kid to stop being stupid and use a rubber before they end up with a kid.
Aunt Lisa: 'You're gonna be stuck with a kid before you graduate. J-hat on da bozak!'
Cousin Jamal: 'You're gonna be the guy who gets stuck with the baby. J-hat on da bozak!'
Grandma: 'I've seen worse, but this is gonna be bad. J-hat on da bozak.'
