look up any word, like donkey punch:
 
1.
When your left nut starts to mysteriously ache for no reason. When the right nut aches it can be called just "the Claw" but that is much more uncommon.
"Dude my left nutty is hurting!"
"Why? I didn't even hit you there you pussbag."
"Nah, it's the Southpaw Claw. It's a bitch."
"And how!"
