fannit 

Synonym for "fantwit" and "fanbrat", a slightly derogatory term used in place of other, lengthier phrases, such as "hyperactive rabid fangirl(boy)".

Fannits generally have the writing skills of a twelve year-old AIMer.

I was talking to this kid online, and man, she was a total fannit.

Fannytastic 

Fannytastic can be used to describe an action or person, in a situation where plain old "fantastic" doesn't have the magnitude to convey the importance.

Being Fannytastic can imply a lack of restriction within imagination, suggesting that someone who is Fannytastic has magnificent ideas that could take you to the moon!

Correct usage in a sentence: "Did you hear she’s picking up her life in France to move to Australia?"
Response: "Damn, that’s Fannytastic!."

Haley is such a Fannibal that she has an entire tumblr devoted to the Brian Fuller "Hannibal" series.

Fanning His Balls 

Slang term for wasting time, doing nothing, sitting around with no purpose. There is an element of laziness involved also because the insinuation is that the person wasting time is staying comfortable by creating a breeze that wafts over his balls.

Q. Have you seen Frankie?

A. Yeah, he's home fanning his balls.

"Fannibals!"
