Tunnel Snaking is when you drop your feces on a pan, then either heat it in the microwave, oven, or with fire, until it is almost completely solid. Then you forcibly insert it into the anus of somebody you wish to degrade. You leave it their and wait until they need to make feces, then they have to poop out both of the feces.
Yea. David was being a bitch again, so I just went into the kitchen and warmed up my shit, then came out and tunnel snaked him till he cried and his asshole bled.
