Roundhouse Fart

Similar to a roundhouse kick expect in bed, when you’re all worn out. All of a sudden your right leg gets a burst of energy launching your right knee into the air projecting gas which delivers a final blow to your blanket before a deep slumber.

Shrek: HIT THIS REAL QUICK! IT’S CALLED THE ROUNDHOUSE FART.
Fiona: These are what the locals use as a useful hallucigenic.
