Define The Greatest Boyfriend Ever Meaning

Usually what dozy, half-conscious, in-a-daze teenage girls say about every boy they go out with, often on facebook (in their status or on their profile page).

This is usually followed by 'I hate x', 'x is the worst boyfriend ever' or 'how could x/he do this to me?'. These comments are usually brought on by the guy dumping her after a good long run, and because the girl is so blinded by love, she fails to realise that teenage relationships were never meant to go anywhere further than a couple of weeks of teen sex because most guys are smart enough to know that the girl they choose to go out with has a long list of flaws that would make her incompatible in a proper adult relationship with them, and are only interested in the short run, as they should be.
