This is The Underground Rebel Bingo Club.

If you don't know who we are yet it's because we didn't tell you.

"It's a raucous night of drinking, swearing, dancing and of course rebel bingo. It was started by two guys in a basement and is now an underground phenomenon"

The Underground Rebel Bingo Club is a secret organisation that meets in secret locations to party hard and play hardcore Rebel Bingo. It's basically the most hardcore form of bingo ever created.

The nights feature:
Keeping secrets - Dancing - Drawing - Listening to music that is too loud

Due to the dangerous nature of Rebel Bingo we have to keep our operations secret from the authorities. The cover story and exact location for this meeting will be issued nearer the time.

Shhh. Do not tell anyone. We are everywhere. And we are nowhere. And where ever we are we are playing hardcore rebel fucking bingo.
