Everclear
There are two kinds. 151 proof, and 190 proof. It is illegal in some states. It can be used as an antiseptic because of it's high alcoholic content and is the best cleaner for the restoration of tabacco smoking pipes. It is a neutral grain spirit. It should NEVER be consumed straight.
Bob: Dude. What happened last night? (after waking up with a massive headache.)

Fred: You had the brilliant idea of drinking Everclear straight from the bottle last night and now you're paying for it...
