Back the truck up

You've had a massive night out on the piss and you're gonna do it all again tonight.

I know you got bat faced last night mate, but are you gonna back the truck up tonight?

Really really drunk. As drunk as a skunk. Pissed off your head.

Dude! You were soooo bat faced last night. Are you gonna back the truck up tonight?
