This person acts like a gay person. They probably do not have friends and they stay away from girls. Other than that, they are very kind.
An evil cheating manipulative bastard, a Jerry’s nature habitat is at bars, parties and other places with large amounts of alcohol. This the place were they will attempt (and hopefully fail) to convince your girlfriend to ass fuck him in his ass. They will attempt to achieve this in a variety of ways but the most common tactic they use is to simply get you both drunk. A truly evil being.
