mr. macphisto means: One of Bono’s lead singers, Mr. MacPhisto was one of his U2 alter-egos. MachPhisto is the Devil’s rock star who is trying to get a decent end in Vegas. After The Fly’s evil, he is The Fly. His megalomania and self-obsession, as well as his lust after power, has led to a lack of wealth and legacy. It is not clear why Bono decided to play this role, but it was obvious that Mr. Machphisto didn’t continue his tour after the Zooropa ended. (in Community Dictionary, added by Belen Beltran)
