common decency

Respect for people around you.

at least, I had the common decency not to blow your boyfriend at our sister's graduation. I waited till after.

Common decency

Something your boring roommate says to you when he doesn’t want to hear your bangers at 11:00 am on the day of the only darty that he will ever have the pleasure to enjoy.

“There’s a thing called common decency, and I don’t want to hear your music at 11:00 in the morning because I’m lame. Hee hee.”
