Shake Weights really only serve one purpose: improving your stroke game.  For women, it's a chance to really work on their form for Ol' Reliable HJ.  For men, it's just mastering the joystick.  Thankfully, these guys took to the streets to mess with some innocent folks.  And boy is it hilarious.

I will never forget when South Park mocked the Shake Weight movement.  It was probably the funniest episode I had ever seen.  These broheems definitely give Matt and Trey a run for their money.
