A Myspace pose is also a good indicator that a girl is fun (meaning interested in sex) and doesn't demand much taste or sophistication.  I've been on way too many dates with women who turned out to be wine snobs, music snobs, fashion snobs, literature snobs, or even TV snobs, who lost interest as soon as they realized I didn't meet their particular snob standards.  People who are committed to being "better than" in any way would never post something as cliché and tasteless as a Myspace pose.  Honestly, for the long term I'm looking for someone whose snob standards are sufficiently aligned with mine, but sometimes it's nice to go out with someone with no standards.  (Actually, they have standards, but they're the kind of standards that can be applied before agreeing to a date.)
