look up any word, like trill:
 
1.
Pronounced: fuh-LAH-sho-rap-ter (similarly and with allusion to the dinosaur velociraptor)

A person - either male or female - who performs fellatio in a vigorous or ferocious fashion; i.e. ravenously like a raptor.

To qualify as a definitive fellaciraptor, the person's arms should be held in front of their chest, with elbows down and wrists dangling loosely; i.e. like a true raptor.

Because of her religious upbringing, I didn't expect Becky to be enthusiastic during oral sex - but lo and behold, she's a regular fellaciraptor!
