Top Popping

When a girl's boobs start to fall out of her shirt/dress (generally of the low-cut variety).

Girl 1: So how was your date last night?
Girl 2: It was great until I started top popping in front of his parents! They must have thought I was a total slut.

top popping

Popping your head up higher than the windshield while riding in or driving a convertible.

I put some pillows under my ass, and I was top poppin' all the way home!. I had bugs in my teeth from top poppin' all weekend in my convertible. Always wear proper eye protection when top popping. I was top poppin' with my gf, and she decided to take off her top for a double popped top experience!
