Shakeweighted

When a girl gives you a really hard, fast-paced handjob, as if your dick was a shakeweight.

Could result in severe discomfort, chaffing, and difficulty shaking your dick after pissing.

A work-out device, believed to be bogus, that when used by a woman, according to South Park, helps them give the greatest old-fashioned (handjob)

To aggressively beat thy meat like silverback gorilla

Not to be confused with the vibrator, I mean dildo, I mean workout assistant, shakeweight refers to the excess ground marijuana that's left in the grinder because it won't fit into the fatty when rolling a joint. In an ideal joint rolling sesh, there would be no shakeweight because the roller of the j knows what he's doing. Shakeweight only accumulates when a gross overestimation was made, resulting in excess ground weed left in the grinder that can't fit into the joint.

Giving such an agressive handjob that you snap their dick off like a celery stalk.

A man that does shake weight classes with his grams and thinks he is buff
