When you get too close to the edge of your mattress and it goes in your arse crack.

Mike: Bro, how was your night last night?

Paul: Dude, we got some serious action, but three adults in a single bed? I ended up mattress cracking all night!

Crack Mattress

Mattress, preferably dirty, without sheets that a person actually sleeps on, similar to what one might find in a crack house/den

"No clean sheets?!!Well, looks like I'll be riding the crack mattress until laundry day".
