Senioritis (as told by high schoolers)
Senioritis is basically just being a lazy ass and avoiding all your responsibilities.
when I'm a senior, I'm going to work hard and finish everything early and on time so I don't get lazy and fall into the trap of senioritis
PSAT, SAT, ACT, AP, FINALS, I give up on everything, I'm ready to leave high school. Gotta get ready for college and apply next fall!
