End of semester celebrations that occur on the last day of classes and generally involve excessive and early morning drinking, denial about upcoming exams, puking and rallying, and the making of poor life decisions. Spring blowout is generally a larger ordeal, as the weather is conducive to outdoor drinking and slip and slide and seniors like to return to their freshmen dorms to give it a little toast. Like many great legacies, such as full-contact beer pong, this festivity had its beginnings at the College of William and Mary.
"Hey, we've got to find a freshmen to let us in to Yates dorm for spring blowout this year. The administration is hardcore about locking down all the freshmen halls so we can't work havoc."

1. Melbourne/Australian slang for a GHB overdose. Can vary greatly in severity. Passing out uncontrollably and loss of motor skills are the most identifiable symptoms of a non-serious case. More serious cases involve vomitting and loud indecipherable yelping or yelling. Can result in death.
2. Someone that frequently overdoses on GHB.
1. Carl: Did you see that dude blowout outside.

Paul: Yeh. What an arsehole.
2. Frank: Have you spoken to Sam?

Sean: No, he's a filthy blowout.

An uncontrolled, poorly contained and always catastrophic bowel movement. Usually the chuncky runs. So bad that even heavy pants can't hide the mess. Food poisoning or a very disagreeable meal are two main culprits for a blowout.
In line at the McDonalds:
Joe: "Oh Jesus, Oh..."
Mike: "What? What's wrong?"
Joe: "That toddler in front of us."
Mike: "Toddler? Oh my, fuck .. Oh the smell."
Joe: "Hey lady! Your little crotch dropping seems to have had a blowout."

Melbourne, Australia slang for a GHB/GBL (juice) overdose. Often comes with involuntary sleep/passing out for hours, involuntary movements, sex with anythng or anyone, extreme horniness, moaning and groaning, dangerous driving and dancing like a fuckhead whilst touching oneself. The person "blowing out" will be unable to comprehend or understand you telling them to "calm down" or "stop it" and will continue to blow out until he GHB effects wear off.

Occurs when stretching of the ears with gauges. It is the extra flap of skin that is created when either going up sizes too fast or when you skip sizes. Blowouts can heal, but it requires the plug to be taken out. Most people think they've gotten a blowout, but in reality they've ripped their ears. Ripping of the ears may have skin discoloration around where the ear was gauged. A blowout mainly happens when the skin does not easily stretch and is forced out through which ever way you're stretching your ears. This excess skin may eventually deteriorate. The results of a blowout (depending on the size) may look unpleasant when the plug is not in.
Person 1: That man's lobes are huge!
Person 2: He's most likely going to get a blowout soon.
