someone who'll post a picture of themselves on myspace from basically a different era in their lives, i.e. a really skinner period in their lives whereas now they're really fat and barley recognizable. A fake, false, posing individual.
Man, did you see Laura's myspace page?? She used that picture of herself back when she was in high school... Seven years ago and before she had 5 kids!!

Damn, what a myspace poser!!
