APCSD 

The school district of Averill Park, New York where students can scream the N-Word and not get in trouble. Here, you will see fifteen-year-olds making bank by growing their own cannabis in the woods.

If the APCSD cooking ladies don't have that speedbag arm fat, you know your lunchtime munchies will be ruined by shitty food!

APTSD

The feeling waking you up at night that you got a 0 on the ap test even though you know you get a point for writing your name.

Teacher: you still have a final after the ap test

APCS 

1. Abbreviation for AP Computer Science.

2. To give up all hope in something (usually work), which is usually accompanied by getting off task and not doing anything productive, or by going crazy and smashing or throwing something in an indescribable rage.

Aaron APCSed his chemistry and computer programming work. Instead of doing work, he just quietly washed glassware in the back sink away from his lab partner, and looked at Pokemon glitches and pictures on Google images.

Andrew APCSed his computer programs by yelling cuss words at his computer monitor and breaking his pencil.
