Jankerbating 

Going into a port-a-potty in 100+ Degree weather and trying to rub one out while smelling festering shit inside.

soldier one "Yo, that port-a-potty is like a sauna"

Soldier two "I bet, its 120 degrees out here"

Soldier one "Yeah, that thing was perfect for Jankerbating."

Jackerbating 

Hardcore, wrist tiring, cock swelling jacking off to the extreme.

Hey man, sorry I can't go out tonight. Why? Well, I can't walk... well it's because I've been jackerbating since Tuesday and my cock is chaffed and balls are swollen.
