Cabin Door 

A synonym for the anus

That guy looks like he wouldnt mind taking it in the ol' cabin door.

That chili was so hot yesterday it burned all the way out the cabin door.

Keeping the cabin door closed is the best policy when in prison.

Cabin Door 

The seal of your rectoanal sphincter between your descending colon and the outside world.

My squeaky cabin door kept me up all night after demolishing a bag of jalapeno potato chips.
