APT

A tongue-in-cheek backronym for "Academy Placement Test", criticizing how addictive the K-Pop song APT. (standing for "apartment") by Rosé and Bruno Mars that this song is prohibited for students to listen whilst studying for CSAT (College Scholastic Ability Test)

Man, that new K-Pop song APT. is so catchy, I joked that it should be renamed to 'Academy Placement Test' since it’s banned during study sessions for the CSAT!
