fracky

When a person is in a freaky, weird, hyper, sugar-high, edgy, mood they are all of the above.

Twitchy, excitable, weird, hyper, laughing for a long time until going blue in the face... like weirdy, but not. har har.
Being fracky.

"Hey, you're getting a little flacky today."

Over use of facts to try and make a point.

Fucking Wacky, not just plain wacky. Totally weird and/or cool. (Always a positive, never a negative.)

"The vibrations feel fwacky against my ass and I'm pretty sure I like it."
