Someone who toot's their own horn. Usually at work, these people have nothing good to say about their co-workers but praise their own glory. They are sneaky and often are very sweet. They move forward within companies unless the employer is a good judge of character. These people always think they're better than everyone and often have their superiors snowed. Not nice people at all, very similar to a back-stabber.
Tom did an awful job on the payables this month, he doesn't know a debit from a credit!
I sure have a good handle on the payables, they're clean and I know a credit from a debit unlike Tom, "hee hee hee I'm such a horn tooter and I have them all snowed, Tom will be gone in no time flat"
