Define Good For The Gander Meaning

Good For The Gander
When a guy does something fucked up to a woman and has the grandiosity to think a woman can't or wont do it back to a man. Yet she does and even raises the stakes on his punk ass.

My boyfriend thinks I don't know he goes to strip clubs when he's out of town. That's okay, cuz the hot guy down the street turns out to be quite good for the gander on those occasions.
