OB
This stands for Outlaw Biker. An Outlaw Biker is the type of guy the girl of your dreams goes and fucks because you're too much of a pussy to take control of your "relationship" with her. Most of the time he is either unemployed, has a substance abuse problem, or has callous "dating" habits. A combination is certainly possible, too. Commonly used to conjunction with "IW" or "intellectual whore" which is exactly what you are if your dream girl fucks OBs then cries to you about it.
Last night I told Jane that I loved her and I'd do anythng for her. She said "let's just be friends" then went home and fucked an OB she met at the bar. She called me up later to cry about it, and I listened to her because I'm a nice guy/IW.

Short for "Legion" contrary to popular belief that it was "Oberon" Rumor has it that it originally stood for "Oberon" but was changed once it was discovered that in mythology Oberon is a sword-wielding fairy-boy.
"Hey has anyone seen Ob around?"
"Oh you must mean Legion."
