acronym for Alternative Learning Center, similar to a detention during class
I was being a rebellious, defiant, idiot in 6th period and got sent to ALC
messing around, not doing what you are supposed to be doing. usually in the back of a class room.
Teacher: "You're all getting F's in this class because all you do is play tickleass back there!"
Student: "Thats fucked up!"
Teacher: "Go to ALC!"
the game played in the back of a classroom between two extremely bored students, often resulting in ALC (Alternative Learning Center), a low grade, and a very angry teacher.
Mr. S. hates me, he sent me to ALC for playing tickleass with Kishan 7th period.
