So I watched Twilight

The first one. It had rifftrax so it's all good.

I don't understand, why do girls like this? I mean I understand why they like chick flicks but Twilight is just horrible no matter what.

"I KILLED PEOPLE, I WANT UR BLOOD"
"LOL ITS OK I TRUST U"


"I BREAK INTO UR HOUSE AND WATCH U SLEEP AT NIGHT"
"LOL UR SO CUTE EDWARD"

So can someone explain why would anyone like this?

There is a common theme being shown from your examples:

Bitches want what they want when they want it.

Thus their inconsistency is actually consistent.

Here is an educational video again exemplifying such behavior.

Now that this is addressed, please don't use /prog/ to complain about bitches. I can get enough of that elsewhere on the internets (same rule also applies to hot bitches--so please no more Leah Culver).
