onehand 

A reference to the size of a female's ass. The size must be small enough to hold her ass in one hand. This type of ass is enjoyed by mostly white males, but there are a few exceptions among black males.

"Dude, that chick had a "onehand". Her ass was so small and tight I gripped it with one hand while I was munching away."

Too Much Rock for One Hand 

A gesture made by clenching both fists, extending the left and right pinky together simultaneously, and placing the fists side-by-side, resulting in an exaggerated form of the traditional "horn hand"/rock hand signal. Often done to convey a sense of irony.

"Duuuude! That Darkness album is frickkin' sweet... it was TOO MUCH ROCK FOR ONE HAND!"

One Hand Technique 

The method used to unclasp, unhook, or otherwise remove a bra with strictly one hand. It's thought that being able to do such an action will largely impress a female cohort and convey that you are smooth and suave

"I couldn't remove my girlfriend's bra with one hand, what do you do?"
"My one hand technique essentially requires me to snap with the clasp between my finger and thumb."
