Person 2: Where did you find her? The Red Light District?
Person 1: What? Are you jealous?
Person 2: Fuck you! I can get one, I just don't want to...
In conclusion, a girlfriend is a female that (particularly in the initial stages of the relationship) you want to make feel special and wanted (not rejected/unwanted) by showing her affection through the simple act of a passionate kiss.
Male: Leans over and kisses the girlfriend passionately then leaves (all without going for grabs or wanting to get lucky).
When experienced, males tend to exert feelings of hatred towards 'girlfriend' and exclaim indicated hatred to others. Remarkably, he will never mention a word of this to 'girlfriend.' This phenomenon must be directly linked to the mind control powers only bestowed by the vagina.
These mind control powers are the bane of males, and are only known of when one is already choking on the tainted waters called 'relationship.' And it seems, even when informed, the male will deny any such power over him until the previous stated situation occurs.
One can only say "I told you so."
