An expression of celebration after an absolutely
sick play in a video game, sport, or just a generally
sick moment in real life. The term is said enthusiastically, and should always be before an exclamation mark. It is very effective when said after a
sick 100m snipe as well.
Fonz: APOINGUS! HA! You

Bavid: Cmon man, you know I can't
beat someone as legendary as you. By the way, you and toucan's ex would make a great couple.
