The term was first coined in the autobiographical book `Candy´ by Luke Davies (and subsequently the movie `Candy´ starring Heath Ledger and Abbie Cornish), when the character Casper (Geoffrey Rush) a lecturing chemist & sometime opiate user synthesizes his own `Golden Jesus´ (diacetylmorphine) from Panadine Forte.
A man who is superior to yourself in several ways (either perceived or otherwise), who is currently dating a woman you are interested in. When he is better looking/smarter/wealthier/more educated/more adventurous than you are, he represents an idealized version of manhood or a picture of maleness that other men are expected to reach but realistically have little chance of doing. Hence, he is an example of Man-Jesus.
Yeah, I'd ask her out...but you've never met her boyfriend. He's Man-Jesus, I don't measure up.
Evil Jesus is a nickname for the infamous E+J Brandy, everyone's favorite bum liquor of choice! Dirt cheap and 80 proof, this is what the dead beats living on the streets drink, and is also favored amongst generally income-limited folks such as most of those in NJ and rappers trying to make it this day in age.
