Derived from goose-feather or cuckoo feather (cuckoo bird), a feather, or a feath, is a crazy-person. He or she is usually out of their mind and in their own world, but not
all the time. They tend to "feath" out or "flap" around wildly. When agitated, which occurs often, feathers can become ruffled. This is also detected through the
possessed, wild-eyed look of the feather. A flapping sound can be used to
reference the actions of said feather or the presence of a feather.
"That girl at
the party was a total feather."
"Did you see that guy
on the bus feathing out?"
"Dinner was great, until I got "feathed". I am not sitting next to Bob's sister again."
"Feath came over last night, and was flapping every which way and left feathers all over
the ground!"
