20

Used after a noun to describe it in the superlative. Derived From Championship Manager and later Football Manager stats, in which 20 was the maximum a player could have for any given attribute.

md 20/20

Very inexpensive, delicious wine that comes in 7 or 8 fruity flavors. Wrekes havoc on the guts of some, but how can you bitch about getting wasted for less than $3? The flat bottles feel good to drink from as well.

I'd like to be able to squirt a turkey baster of md 20/20 directly onto my brain each day before work.
