SOB
Self Obsessed Bitch.
A SOB can generally be found in the bathroom, preening in front of the mirror, trying to make her dress look even shorter or wiping off the make up that has run down her face while she was puking out the results of excessive alcohol consumption. Her only purpose for alcohol abuse is to have an excuse for ridiculously whore-ish behaviour. Smoking is another bad habit of SOBs, however her purpose for smoking is not to inhale niccotine and satisfy a craving, but rather to appear sophisticated and hardcore (more like whorecore). She enjoys commenting on photos from the night before, trying to highlight how 'totally normal' her 'party girl' lifestyle is. In the SOBs early life she has been the opposite of what she is now, and undertook this lifestyle for the social attention. Everyone around her thinks she is drunk attention seeking whore. Guys however can be blinded by the whore-ish behaviour and excessively revealing attire, leading the SOB to entertain many a drunken hook-up. SOBs are later offended when said drunken hook-ups refuse to acknowledge their participation in such hook-ups. Once again proving the flawed mentality of the SOBs desperate lifestyle. If you should happen to encounter a SOB, you might want to give her a condom to prevent the unnecessary spread of HIV. Or just kick her drunken ass out of the party, improving the night for everyone involved.
Girl 1: Look at that drunk girl, grinding on every guy.

Girl 2: Yeah, she's such a SOB.
