Much like a Barry boy, a Gary boy drives around in a car (usually some old model they bought second hand) with the music pumped up so loud that it shakes houses as they pass. Have often modified car's music system by stuffing speakers into the boot ect.
I was woken up by some Gary boy driving past the house at 2 in the morning, the music was so loud it made the windows rattle.

"What did you do that for"
"Because I DNSDC!"
"Because I DNSDC!"

If you were to have two choices, and one involved payment and one did not, the one that did not involve payment would be free-er then the other.
