When one says they will take their significant other to dinner but then bails at the last minute. This act is often followed by a 5 minute fast food trip and an unawareness of what they did wrong.
“He promised to take Cheyenne to dinner for her birthday, but he ended up Pulling a Sully, took her to Moe’s and went to the gym.”
Verb, to grossly over-exaggerate. Usually this is with a fact or experience. To properly pull a sully, you must always reference a certain website or source, which can never be found at a later time. This practice is extremely annoying.
Guy 1: Have you heard about the new Audi Q 5? It's diesel gets 81MPG! I heard ti on the Audi website!
Guy 2: I don't think so. Let's check that website.
(Website says it gets 25 MPG)
Guy 1: I could have sworn it said 81! I must have read it somewhere else!
Guy 2: Shut up. Don't pull a Sully on me.
