Einstein Line: Common vernacular of regular concert goers. The Einstein line is the front row of the mosh pit where the punters stupid enough to get caught (Hence the sarcastic allusion to Einstein) are mashed up against the security barriers protecting the artists on stage from the audience.

Has recently entered popular slang as the front row at any live concert - security barrier optional.
Wayne: "Woah Garth, check out that chic in the Einstein Line, she's lookin' pretty mashed up!"

Garth: "Like, yeah, she's like, a bonafide honey! Party Time! Let's bring her on stage man!"
