an mma submission performed from half guard. created by making space space between you and your opponent. move under his armpit and sit up, so now he should be behind you on all fours (but still in half guard). cross your calf into the back of your opponents knee and grab his toes and pull back. The higher you grab on his foot, the more it hurts
"Junie moves from half guard and goes to take his back, Oh a Calf - cutter out of nowhere!"
