nuts lock up

When a male moves his lower abdomen, lower body in a way that causes his " nuts to lock up", or get tangled internally.

My husband was so busy being an asshole, by waving his legs at me while sitting in a lawn chair, that he maneuvered his "nuts lock up" from the rapid movement of his lower body; later requring surgery to be correcred..LMAO #KARMA

Nut Up

Verb phrase: To involve oneself in a physical altercation, to lose one's cool, or to fly off the handle. A common fixture of urban or "gangsta" vernacular. Recently popularized by a homophobic, black-clad drug-dealing NPC/pedestrian in the controversial PS2 game "Grand Theft Auto: San Andreas."

Nut Up or Shut Up

Either walk your talk and prove your worth or toughness, or keep your pie hole shut and get the hell outta town.

Keep running your mouth...either rise to the occasion and let me thrash your ass when I grab that stack of dimes you call a neck, or refrain from further trash talk. Take your pick!!
