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!!

Nut up or shut up 

It means that you either gotta whip your dick out, nut it up, and get your shit done, or stop talking, sit down, and keep quiet.

Person 1: My throat hurts really bad this morning, but I won’t complain. You know what they say, nut up or shut up.
