a Kelly night usually involves the disappearance of clothes- whether it be due to a challenge, a strip ps3 or sport game, or just the annoyance of clothes. It also involves a ridiculous amount of fast food, and of course a ton of alcohol.
"So we ended up playing strip tiger woods and then I woke up naked, with evidence that I ate TWO whataburgers, fries, and a honey butter bisquit spent over 15 dollars.... I had a Kelly Night."
To suddenly, and with seemingly no cause, spill one's shit all over the place. Those who "Pull Kelly's" are often repeat offenders, and cannot be trusted to carry or otherwise posses plates of food, bowls of soup, glasses, mugs, any other similar containers, or basically anything that would be really inconvenient to clean.
generally said to someone when they do something really stupid like turn a corner doing 40 swerve to miss a car and in turn hit a tree which ends up hitting a house. (to be noted she did not get hurt which is why its funny)
Becoming delusional, psychotic and making up absurd stories about people you know. Pulling a Kelly may result in arrest or commitment to a psychiatric facility as well as losing most of your friends.
