jammer Dave

Jammer Dave is the kindest of Mega brojs. Lives on PB&J and mushrooms. He has the tightest of buttholes. He’s a mega-jammer and rips, bobs, tears and weaves. He is the kindest of souls and you only hope you can have his energy in your life, Like a warlock casts spells with sweater puppies.

Jammer Dave loves to mega jam tbh

reverse 360 piston jammer

The advanced art of standing in front of someone, inserting your fingers into their anus, then forcefully rotating your wrist 360 degrees, it doesn't matter if it breaks, slowly insert more of your arm into the anus, then another forceful 360 movement, this time on your arm. Once this is completed, a full bottle of gorilla glue is applied to the arm and anus, locking it in place.

John: Hey Peter, why is your arm mangled?

Peter: Because I hit Dave with that reverse 360 piston jammer!

John: Peter, you're dead to me you retarded nigga.
