Made popular by Techtronic in 1989. Meaning to 'set the dancefloor on fire'. Usually by means of the running man and other late 80's dance moves.

When the driver of a motor vehicle runs the engine up to near full load and speed for an extended period of time to burn off built-up carbon in the combustion chamber. The term originates from Ferrari mechanics who would drive cars around a race track several times after a tune up to get the engine hot enough and subsequently burn off the carbon. Many Mercedes-Benz Diesel owners also use this same technique, too.
After replacing the distributer cap, rotor, and spark plugs and tuning the carburetor in my AMC Concord, I performed an Italian Tune Up to finish off the job.

Sarcastic way of saying that something has gone wrong. Similar to the tooth fairy, but the fuck up fairy leaves mayhem instead of money.

Noun. A person who appears to be of average weight and size based on their face and upper body but who has an ENORMOUS lower half. The term comes from meeting someone at a table and speaking with them for a while thinking that they are a slender person (based on the face and upper body) but then getting a surprise when they stand up from the table and you see their large lower half for the first time - hence... "stand up surprise". The top/bottom differential must be extreme to count as a stand up surprise.
"I was flirting with this girl all night long and I thought she was such a skinny babe, but when she stood up from the table I saw that she had a HUGE ass. She was such a stand up surprise."
