1.
A person who stalks a person and finds out almost everything about them. I.E. - Their new job, where they live, their phone number, etc. But, still like them, so instead of calling them just a "STALKER!!!!", it is more of a joke, so it's "Mr. Stalker Pants"
Teacher: Wow Mr. Stalker Pants, your stalking abilities sease to amaze me.
