Clit Grinder

One of the two ways a female can come to climax, one way being through general intercourse, the other, is when a girl has to be on top or bottom of the man and grinds her clit into the mans pelvic bone to reach climax.

Stealth Grind

When you sneak behind a random person dancing, or ideally some couple grinding on the dance floor and make spastic pelvic thrusts and other sexual gestures (i.e. ass slapping) from behind the unknowing target. Also can be equally effective and hilarious when done behind any person bending over for any reason, as in tying their shoe.

DB is stealth grinding king of the world.
