when someone backs out from a responsibility or commitment because they're
lazy or
don't want to. The first simple definition that came to mind. To remember it, think of it this way: An angry
Karen complains at the nearest police office(don't why but just for this ex.). The officer there named Jerry doesn't want to deal with that rn and leaves. He tells his trustworthy friend, officer
Bob, "I'm out"...or in this case since he's a popo(slang for police), "COP OUT".
Even though Officer Jerry's shift wasn't over, Officer
Bob still let Jerry cop out on dealing with the
Karen bringing her problems to the
police station because he's a good a friend. Kudos to him
