Feathering It 

1.) When you are a cool guy, who knows what’s up, and you just seem to never stop (possibly due to drugs or mental illness).

2.) Cutting your hair with fire.

First Example -
News: Local Florida man was arrested for assault with a deadly weapon after throwing an alligator threw Wendy’s drive-thru window.

Reader: Man he’s just feathering it.

Second Example-
Tom: Dr. Drew looks really good!
Christina: Well, he has been feathering it!

Two undercover cops: well there's been a gang stabbing here earlier and you were 'flashing colors' (wearing all blue).
