When a woman is extremely good-looking but not quite among the best
(This is a slang term used by men with minds in the gutter )

The best, great, nice, awesome, amazing.

Just another new synonym for cool.

What you call a little podgy feller, often with fat all over his body, not just round the waist.

The point where someone moves past just being high, now they're sirloined.

When something is really awesome or totally rad, it is sirloin.

VEGGERS IGNORE!!!!!!!! -legendary hamburger created by one east coast chain, (top's) then absorbed by another (gino's) mid-70's

-when you couldn't get sex, and needed some food after an extended hop-up session, this hamburger was BETTER THAN SEX!!

-this burger allegedly actually had "sirloin" in it!! whatever it had, nothing as dreamy, sexy, and delicious has existed since; fast food wise!! SIRLOINER, R.I.P!!

Refers to the finest type of meat a man can get.
Often the 'Sirloinivity' of a subject is inversely proportional to it's age.
