When you put both your testicles in a hole (pussy, butthole, or mouth) and then another guy also puts 1 of his 2 testicles in the same hole.
Yo Lauren, you wanna come by my cardboard box later tonight so Choad-Head and me can complete the 3 balls 1 hole challenge?

When a girl stands naked, legs together, at the top of her legs, before the naughty bits, there is sometimes a triangular shape where her legs curve back in and there is space between the thighs at the top.

Mainly this is only on tall, athletic or skinny girls, apparently this is ideal when you could just fit a golf ball through, as any bigger is deemed too big, and smaller is deemed too small.
-What do you like most in a girl? Boobs? Legs?

-No man, I'm all about the golf ball hole.
