Matric Dance
Also known as Matric Farewell - Is when grade 12 (last year of high school) learners have one final formal function, often followed by parties, underage drinking and bad decisions. Each school usually has its own dance and pupils usually come with a date and wear expensive suits and dresses.
Americans would call it prom
