Righto mate it’s like this, you’re havin’ a sunday sesh gettin -blam!-in’ maggot with the boys, havin’ a right piss up and it’s fully sick. Daveo and Steveo are settin up the barbie to cook some snags but ya -blam!-in’ gas bottle’s carked it! Bazza’s like who’s keen for a maccas run but you had maccas for brekky and Tommo had it this arvo. Then Archie, the -blam!-in’ mad -blam!- he is, goes hey boys I’ll be DD, piles us into the commodore (SSV cuz he’s on big mobs of cash doin FIFO) and we all cruise down to Nandos for a feed.

Nandos is a fast food chain.. why are you making shit up?

The first sentence of the definition for this in the urban dictionary sums this up perfectly.
