Some random guy walking by: AP MOMENT!!!
When something unbelievably unfortunate happens to someone, whether it's their fault or not, and it feels like the universe is kicking them while they're down.
The act of your voice cracking so often mid-sentence to the point where you feel as though you are going through puberty all over again.
Rob: "yea, so i was with my (crack) friends last night and we were having a (crack) really great time."
Gina: "dude, your voice is crackin so much right now..you bettercheck yourself or something, cuz you're definitely having a bieber moment."
