This is a name for a some guy's girlfriend. Typical guy who calls his girlfriend 'em' is a real beta-male, skinny, has no self-esteem and has a really unmanly whiny voice. That girl he calls 'em' is pretty likely to be his only girlfriend. He is also prejudiced that he can get any girl, based on credential that he thinks she has.
