Tit-to-gut ratio. When a girl has bigger tits than her gut, she has a positive TGR. When a girl has smaller tits than her guts, it's a negative TGR.
All I want to find tonight is a girl with a positive TGR. Do not let me hook with another girl who's stomach is much bigger than her boobs. I'm doneclimbing the mountain to get to her tits.
"I got some π₯π₯ Tgr'aby last night."
"Once we get into Area 51 we're hitting up some hot alien Tgr'aby!"
"Do you think the soldiers at area 51 mess around in some Tgr'aby?"
