11.
A hideously ugly man who pretends to be straight but is definitely gay, and absolutely hopeless at hiding it.
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.
E.g 1) Guy 1 - "Hey check out that that guy over there, he is so gay."

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.."

One of Batman's oldest foes, and one of Bruce Wayne's oldest friends. His first appearance was in Detective Comics #66, in 1942.

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.
From the private notes of Dr. Hugo Strange

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

TwoFaces are most likely the newest designer pills on the black market today, although mainly found in Europe, there is rumor that they will be making it to the states quite soon. The high of these temp. legal pills resembles a high dose of marijuana at first, then transforms into a more psychedelic less euphoric version of MDMA. Pills effects last up to 8 hours and they are commonly found in half red half blue capsules, they usually come with the warning not to take more than one. Witch implies a strong dose of whatever active compound(s) are present. They are not commonly sold as extacy but are similar in price, altho somewhat higher. If you would usually pay 10 - 15 for an extacy pill in your area, expect 2faces(also commonly known as 26's) to go for around 17 - 20.
"Ay man, i just got some two faces, want one? 25 bucks."

"Hell no dawg, i only pay 8 bucks for beans.."

"Bro.. this isnt extacy, its 26s, imagine smoking 4 blunts of dro to the dome then eating a mix of acid and extacy.. thats what ONE is like"

"Let me get 2.."

"Dont die, here ya go."
