A week-long experience for PA, MD, NJ and parts of NY graduating seniors of high school (sometimes the failures tag along for the ride). The week is normally in the month of june. Usually consists of renting from the dirtiest run-down houses to up-scale condos for a week in NJ, DE, or MD beaches. The week consists of straight binge drinking of all different kinds of alcohol from Natty and Guinness to Vladdy-Stoli, as well as consuming (in various ways) cannabis. Random hookups criminal behavior, and disregard for anything and everything are simply unavoidable during this week. From the minute senior week starts, so does the loss of brain cells. Wake up with a shot and go to bed with a bowl and a brew. Wake up the next day and do it all again but better.

Some seniors end up doing a senior summer which is senior week but lasts the whole summer.

After Freshman year of college, the former seniors loved the week so much that they end up revisiting the beaches for round two or even three or four the following years.

A week of non-stop partying of all upperclassmen highschool students in the Greater Baltimore area. Usually taking place from the end of May to mid July, the sad excuse for "partying" is designed for graduating seniors, but immature Juniors who finally got their licenses can go and feel a part of something special.
Guy: Hey, where are we?

Guy: yes please.

The whitest possible holiday for graduating students (high school or college). These people will typically go to Ocean City, Maryland to contract some sort of STI or STD, whether it's from a tattoo shop or from someone else.

Senior Week is basically the drunk child of Christmas, New Years, and July 4th

Can't wait to lose my virginity to a bunch of douchebags

The week-long party that all Baltimore, MD senior high school graduates (and some others) attend where you are throughly introduced to all the things you will have in college: bad beer, cheap vodka, random hookups, old weed. Truly the best beginning of summer. Normally the first or second week in June.
O yea, I remember him. We went to his condo during Senior Week.

Also attended by anyone age 16-21. Juniors in high school take off school for a few days to feel cool and college freshmen go to do it over again right a.k.a Beach Week. No cheap vodka, give us the good alcohol! You make sure you stay in a condo with maid service because you know you are going to be to f***ing lazy to clean. Also, you know not to stay the entire week because you WILL get bored. Seniors talk about this event as freshmen and it becomes the topic of the day from two months before you book your place to three months after you get back. What no one can understand is why everyone goes down to OC to have a reunion when no one liked each other in high school anyway.
Have you booked your place for Senior Week yet?
