1. The point in an evening of drinking where one blacks out from copious amounts of Absolut

1. Jimmy - Dude, was that you running around the party screaming your ass off last night?
Dan - I don't remember man, I hit absolut zero at about 11...
2. George - Is it just me, or has Rob hit absolut zero since he started working as an accountant?
