Put up or shut up 

Basically, time to do what needs to be done or accept the undesirable result of where you are headed.

I've been cruising through life for too long. Now its time to either put up or shut up.

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!!

Stack Up or Shut Up 

A common term a hardcore 2nd Amendment Supporter will tell Anti-Gunners that want to confiscate guns.
Usually, these lefty's want government goons like the Alcohol, Tobacoo, Firearms and Explosives or known as the ATF to confiscate your guns instead of themselves as they are cowards.

Lefty: You don't need your AR-15. We're coming for them.
Average Gun Owner: You gonna come get them yourself? Stack Up or Shut Up!
