Usually, a Two Face is an ugly arrogant male who acts as if he is God's gift to women.
When, after several hundred rejections, he realises that he is actually not attractive to the opposite gender. He secretly becomes aroused by other men, but panics and wishes to hide this fact from the general public. He visits gay bars at night, and acts generally like one straight person during the day and his gay counterpart at night.
Unfortunately, the Two Face is hopeless at keeping his secret, and constantly overdoes the straight act/lets gay things slip until all his friends want to pull him out the closet for him, and ram The Truth where the sun don't shine.
Guy 2 - "What, HIM? But he seems so straight!"
Guy 1 - "Uhuh, TOO straight. We saw him visiting the Manhole Bar saturday night."
Guy 2 - "Gah, what a Two Face!!!!!"
E.g 2) Girl - "Wanna come back to my place?"
Two Face Guy (loudly to friends) "Aw hell yeah bitch I'mma fuck yo ass yeahhhh I'm a playa bitch I LOVE THE COCK!"
*Bar goes silent, everyone stares*
Two Face Guy - "..I meant pussy, bitch..aheh.."

He was once Harvey Dent, the youngest District Attorney in Gotham City's history. However, Salvatore "Boss" Maroni threw acid in his face during a trial, which hideously scarred him and fractured his psyche.
Now known as Two-Face, he has developed an obsession with duality and chance, basing his crimes around the number two, and deciding outcomes of life or death with a flip of his two headed coin, which like him, is scarred on one side.
Two-Face is obsessed with duality, and determined to recruit half the population of Arkham City in preparation for a bloody war against the other gangs within Arkham City. But his strategy starts and ends with a flip of his coin, adding an element of randomness to his every move.
"The world is cruel, and the only morality in a cruel world is chance. Unbiased, unprejudiced, fair."-Harvey Dent/Two-Face
