Upside-down b 

Upside down b - which if you look at it as a lower case, means p, or methamphetamine. This is a common term used in New Zealand, made famous by Bro'Town.
The letter p is likely to be derived from the main ingredient in methamphetamine, pseudoephedrine.

Eh bro'! I can't believe youse got hooked on upside-down b!

Don't forget, make the end of it "Select, Start" if you want to play 2 players!
