Fake Ring

I have an obsession with the group Lonely Island, so when I came across the following video (a parody) I wasn't confused or upset, instead I was intrigued.

If you don't have time to watch the video I'll give you the jist. This website MsTaken.com created Puke in my Mouth, a parody of the song Jizz in my Pants. No biggie, as a female this video was hilarious, and it's been a year or so since I saw it, but I got distracted today and relocated it only to wonder... are fake engagement rings just... wrong?

Why can't women just say I'm not interested at a bar instead of passively aggressively flipping the ring bird at the obnoxious guy who may or may not smell like old gruyere sweating all over you.

This is more of a question. A topic of debate if you will about whether or not the fake engagement ring stands as good or bad.
