1) When your girlfriend or any other girl of interest including a potential bang or even your mother starts bitchin, complaining, nagging, or failing to know her role. In most cases, there is no reason for this act of crumpin and it usually comes out of nowhere.

2) Any annoyance or complaint that comes out of a female's dirty mouth.

3) An accumilation of bitching. Even if your best friend is complaining you can tell him, "Stop crumpin. You sound like my girlfirend."
Girlfriend: "Where are you. I thought we were supposed to eat lunch together today. Seriousy, I'm getting sick of this. Whaaa Whaaa Whaaa."

You: "Bitch...stop your fuckin crumpin'. I'm playin (insert your game of choice {ex: FIFA/Madden} here.) I'll see you later."
