discretion is the better part of valor 

A phrase meaning to not let courage outweigh good judgment; is the potential outcome worth the risk?

Kid (10 years old): I really wanted to punch that boy for what he said dad, but I thought his parents would probably sue us, so I didn’t.
Dad: Wise decision, son. Discretion is the better part of valor. I’m proud of you. What’d the kid say that made you so mad?
Kid: He said mom was a whore.
Dad: What?!... Why didn’t you beat the shit outta that kid!!

doorman discretion 

That immense amount of power conferred upon one without commensurate knowledge, experience, or understanding, such that, in effect, the village idiot ends up holding the keys to the U.S. nuclear arsenal, or worse, won't let you into your own office building so you can finish working on that one document that will define the rest of your career and is due tomorrow morning.

I apologize for not filing that brief brief with the supreme court on time, but I was the victim of doorman discretion.

discretionary taco 

When ordering food for a group at a taco joint, it's a good idea to get an extra taco, just in case someone is extra hungry!

"Oh man I finished my food but I'm still hungry!"

"You want the discretionary taco?"

"Hell yes!"

"Mild, hot or fire sauce?"

Viewer discretion is advised 

The modern-day version of the "ladies and children not admitted" pre-performance advisory-message used by The King and The Duke to lure a larger audience to come and see their pathetically-mediocre shenanigans.

Nobody will ever admit it officially/publicly, of course, but everyone secretly knows that posting da "Viewer discretion is advised" cliché actually has da exact opposite effect for most people --- it makes them all da miore fired up to watch said media! And then of course after it's all over, like as not da viewers bewilderedly glance at each other and say, "That's ALL?! They considered THAT to be too "mature" for younger folks?!?? Why, that wasn't even as bad as da stuff they show middle-school kind in da couyrse of their lessons on history, social studies, science, chemistry, and stuff! Zheeeeesh.... da producers musta given it that rating just to lure people to watch their insipid mundane crap!"
