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".

Mattress Cracking

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!
