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 Dick Pic 

A not so typical picture of a dick taOR from approximately knee height (easier to take with longer arms or while squatting) angled in the upward direction in order to showcase both the nuts and dick. Be sure to have an erect dick or run the risk of appearing to simply have three nuts. Be sure to avoid anus, but if not possible, be sure to cover with emoji.

nut up 

(v.) To gird ones loins. Nutting up entails using one's proverbial balls or "nuts". Mainly used on the US west coast, it's the sister (brother?) term to cowboy up.

I better nut up or I'm gonna get my ass kicked in this fight.
