not kosher 

The phrase used when someone does something that most people don't agree with; socially unacceptable; politically incorrect.

This phrase cannot be used in reference to dill pickles, because I'm pretty sure those are always kosher.

Jack: John, are you stealing those little kids' lunch money again? You're like 40 man you need to stop that.

John: (Looks down at his feet with shame)

Jack: Not kosher man, not kosher at all
