When we reach senior year, we just don't give a damn anymore. it's over. we're better than EVERYONE, including the school's staff. We're unbeatable and immortal until August when we become freshmen again.
-You and 26 of your closest friends pile into a girls' purple hand-me-down minivan, stop at another friends house, steal alcohol and proceed to your basement to play beer pong and take shots. All before 11:30 am.

-"Wait, where is this cafeteria you speak of? is it anywhere near McDonald's?"

-"How do you cure Senioritis?!"

"Not sure man, hit this L while we ponder that thought."

to go out when you know that you shouldn't because you know that you will never be able to be this ridiculous ever again---because if you do, everyone will be telling you that you need to check into AA and/or get some serious help
-What do you want to do?
-I don't know its rainy and gross out and a huge storm is coming in, and I have a test and lots of HW to do, so probably nothing...why, what do you want to do?
-BE A SENIOR! Lets go out and get wasted!

An attitude that high school seniors adopt anywhere from the start of the school year towards the end. Symptoms include a decreased motivation to do homework, study, or even pay attention during class. Frequent absences and/or tardies are common. Basically when you are infected you do not care that you are infected because you have lost motivation to care about anything. Senioritis is a form of being burned-out on school and the same routine you have had since you can remember.
"Bobby, you have had 6 absences in the past month, have several missing asignments, almost all F's, and you just sit there doing nothing. What are you doing with your life?"

"I don't know or care; blame it on the senioritis."
