Similar to a High-Five, the Low Two is when two dudes' balls slap together in the act of double penetrating a woman.
Yo, Jeff, gimme a low two, cause this hood-rat can take it to the base!

A low two is when a man's balls smack a female's bottom during a celebratory final thrust after great sex. Like a high five.
L: We had to low two after sex last night; it was that good. Balls deep with a satisfying smack!
