When an experienced anal sex taker has an asshole that can fit a louisville slugger in it and looks like you will fall into an abiss.

-in essence its a stretched butthole that is no longer tight.
I watched a porno and the girls asshole was an assbiss, it was no longer tight.

I wanted to anal this bitch and she had an assbiss.
