two blocker 

The definitive sound system for a car driven by a bogan. Usually associated with Australian western suburbs, a two-blocker is a car fitted with fully sick sub woofers and stereo system which can be heard from at least two suburban blocks of the sounds origin. Sadly, 99% of the music is of the 'doof-doof' variety. Drivers of a two-blocker have other interests such as "even more fully sick cars with louder two blockers"

"Ahhhh yuleh, I fully heard this sick two blocker pumpin' past the house"
"Sick, what a siiiick c**t"
