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.
Dude my dick hurts so bad after my girlfriend gave me a hj yesterday. I can't even feel my dick.

Sounds like you got shakeweighted.

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.
bogart: i have so much extra weed that i can't fit into this joint. I don't know what to do...should I just keep the extra weed in my grinder?
