jack brady
When you sneak up behind a girl and tweak her bra from the back of the classroom. Mainly done by guys who think they're slick, but everyone knows they're just trying to impress their crush.
I tweaked her bra and she screamed like a banshee.
He tweaked my bra in year 10 and I still hate him.
I did a Jack Brady and now I'm the class clown.
