Reebock-wearing, mulleted person in acid-washed jeans and a Judas Priest T-shirt who, at the age of 28, still lives in his/her parents' basement and swears that he/she can really rock out on his/her Ibanez Stratocaster copy guitar and probably owns a Nova that hasn't run in 5 years but you just wait, that fucker is gonna smoke those fuckin Japanese rice burners once I put a new head gasket on it.
When are those heshers going to realize that it's not 1989 anymore?
An exclamated expression used to comment on a women's breasts. (Ace meaning 'excellent,' racking meaning 'breasts'). Can also be used, oddly enough, for anything that is good. This expression developed in Oyster Bay.
'Dude, check out that ace rack on that girl!'
'Dude, this band is surprisingly ace rack.'
'My hat is like, totally ace rack.'
