Smack your hands against your body repeatedly, mainly the torso to chest area, and continue to smack hands on body and say "hambooooniiinngggg" in Rigby's voice from Regular Show.
Rigby: HAMBONINGGGG
Mordecai: No...
Rigby: HAMBONING WILL SAVE YOUR LIFE ONE DAY!!!! It'll be like "what! you tried to mug me?"
*proceeds to hambone for 20 seconds*
Mordecai: NO! We're not doing that, okay!? Okay!?
Rigby: Fine...
A cool-ass superpower used to kill 3 burly half naked Aztec men and send the other one flying into space. It also almost killed a gay immortal vampire lord before he cut off his own damn head. It's so beast a nigga can manually break his arm to gum-gum rocket a bitch in the face without pain. Even Speedwagon is impressed.
Jojo! This is the last of my hamon! Take it from me!
This Araki Hirohiko guy uses hamon to stay young. Ain't that cool?
the country side of halifax, where babys become men by learning how to ride dirt bikes and four wheelers at the young age of fetus, and a couple years down the road they become potheads and alcoholics. like a dude wearing black airforces, these people are no-one to piss off as you'll probably get your ass kicked.
