Universal descriptor, applying to any situation. The connotation depends on the situation. Other variations include toyoterish, toyoteric and super toyoter.
It's an old expression actually originating from a peg, with the Rooter being the snout, and the Tooter being the tail. So basically it means the whole hog from snout to tail. But has come to mean from head to toe.
A person who divulges personal information about themselves, completely unsolicited; to any and everyone at will.
