When a women's vagina is very very loose, it is said to be 'gapped out'.

This is sometimes the result of genetics, however, it is much more commonly associated with whore-ish behavior; slutting around like a hoebag, banging dudes like a dirtleg, getting blown up like The House of a Thousand Cocks, etc.

The gapped out woman may have trouble keeping tampons inserted, or may be unable to tell 'if it is in yet'.
I finally banged the office skank - that slizz was so gapped out, it felt like throwing a toothpick into a volcano.

Get the gapped out mug.
To lose focus and completely forget something.
"Oh man, I totally gapped out on picking up my girlfriend from the bar!"

"I'm such a fucking gap out, I didn't hear anything you said"

"Sorry about that, I totally gapped"

Its is to be lost in space, to have very little brain function and have no awareness of what is going on around you. Commonly happens when a person is stoned/and or driving.
Person One: "Did you hear what I just said?"
Person Two: "No sorry I was gapping out"

Get the Gapping Out mug.
To become distracted from the task at hand and focus on another idea of a different tangent.
"I didn't hear a word you said, I just had a massive gap out!"
