Unhealthy Boy Obsession Syndrome

When you just happen to know everything about a boy that there is to know. Their address, their age, hobbies, grades, personality, what their house looks like on the inside, their families names, you stalk their social networking sites to the point where they will find out eventually even if there is no legitimate evidence you were on their page.

Some results of this could be bad like them thinking you are a creepy stalker, or a freak that will never get a boyfriend.
