A type of challenge where two people get together and start jerking both of there meat like crazy, until someone busts. The person who busts first looses.
“Wanna have a jerk battle?” “Sure!”
“Bro I beat this old man in a jerk battle, he jerked so hard he turned his own life support off”
When you pleasure yourself after eating a bag of hot Takis chips, so your hands are covered in the spicy dust as you jerk off, this term was coined by Arin Hanson of Game Grumps
