1.
When you've had a couple of drinks and get in the mindset to throw as many drinks down your neck as humanly possible, then inevitably do something stupid like beat up a pregnant woman or crap your pants.
"You better go and hide all the sharp objects, Lamberts got a massive Drink-On"
"Did you hear about the Drink-On Brady got last night? He drank a pint of vodka and then smacked Susan in the teeth"
