An unusual person who likes things you put on facebook, and may or may not make you uncomfortable. If you're okay with it, then probably the term is used endearingly, otherwise it's used when full of hate. It's sort of like calling someone a tickle monster.

You feel like a monster after you listen to the Skillet song Monster and it gets stuck in your head so you are now quietly singing to your self "I, I feel like a monster!" while doing the dishes or something.
I feel it deep within, it's just beneath the skin, I MUST CONFESS THAT I FEEL LIKE A MONSTER! I hate what I've become, the nightmares just begun, I MUST CONFESS THAT I FEEL LIKE A MONSTER! I, I FEEL LIKE A MONSTER! I, I FEEL LIKE A MONSTER!-song lyrics from the song Monster.

When one has to pee really bad, they have to pee like a monster. When you have to pee so bad you can't wait. Having to pee to the extreme. Getting upset because there is no where to pee.
Why is there no public restroom? I have to pee like a monster!
