Flangling 

When a fly has been hit the first time and isn't really dead, he's flangling.

The fly was flangling after Eryn hit him with her piglet slipper.

Flailing Susan 

An advanced position in sexual intercourse involving one man and one woman. The woman, on top of the man, does the splits while hanging from something. The man lies on his back on a lazy-susan, inserts his erection into the woman, and starts to spin on the lazy-susan while remaining inside her.

STRETCH AND LUBRICATE PRIOR TO ATTEMPTING!

Caitlin: Wanna try the flailing susan tonight?!
Jason: Hell yeah, but let's use extra lube since I got really chaffed last time.
