Pongasm 

Uncontrollable elated singing often caused by the "Pong Flu" which brings out maximum ecstasy for a short duration. This is not to be related to "Ponggasm", which is when a man named "Pong" has an orgasm (during sexual intercourse with oneself)

"Oh my god, what is with all this singing?" A said.
"He must be having a Pongasm!" B replied.
