Ancient Australian Proverb - A Macca's run is a sacred late night ritual performed by all p-plate license holding kids in Australia. It's a trip to the local Maccas at a late hour with you, the deso driver, and one faithful mate to carry all the orders that only half your fucking useless friends have paid for and if you're the only fucker sober at the party it's your arse asking for 40 fucking oreo McFlurry's at 2 AM.
Drunk friends:Macca's run?
Deso driver: Ugh, okay.

I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
