Fat Kid Sinks Last Second Three Pointer

I've got to admit, I'm confused by this video. Did this kid have the OK from the coach to launch that shot? Was the game firmly in hand? This looks like some spare weekend game but we've got two professional looking refs. Is that the word "church" around the center circle? And is that a chick in red jersey #42? And that kid in the plaid shirt who comes running in at the end sure is focused on  hugging.
