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!!
-got all fucked-up then went to gino's and got me a sirloiner!! my stomach went into orgiastic spasms!!

they chased off the sirloiner!! -guess its' back to 'turds on a roll'!!!
