beast of steeton mountain

Giant cat-like beast that guards a mound of hay for reasons not known to mere mortals. Sometimes can be heard whistling a soft, mournful tune from the top of Castle Davy.

Don't hang around on the station at Steeton longer than you have to, the Beast might get you.

Beast from Within

An astoundingly huge and horrible fart; the kind that can clear a room, or even an entire grocery store – a fart from which there is no escape for innocent bystanders.

The act of letting such a fart is to "set loose the Beast from Within."

"Hey, why is everybody leaving?"
"Don't go in there!"
"Why not?"
"Frank just set loose the Beast from Within!"

A man and woman engaged in an act of sexual intercourse. An expression whose usage dates at least as early 1604, being mentioned in Shakespeare's Othello.
