otbc

Short for "On The Ball City!" primarily used in football chatrooms in reference to Norwich City Football Club's anthem, though to be the world's oldest (and subjectively best) football song still in use today.

NCFC Chatroom:
YellaCanary08: "That last game was rubbish, when are we going to buy a proper striker? OTBC!"
BlueScummer69: "I wish I lived in a city."
