Top Definition
When your penis gets too tired to perform and just quits on you. Before a cack crash, your penis will usually be extremely excited like someone pumped him full of caffeine.
Duder 1: "Hey doggy how'd it go with that brizzle last night?"

Duder 2: "Well it started off great, but then my dick just went limp on me. I was all hard at first so I thought it would be an epic f*ck session, but it wasn't."

Duder 1: "Oh man, that's classic cack crash, B. Better luck next time.... oh wait there won't be a next time biatch!"

Duder 2: "Yeah... thanks a lot you dick."
