The younger brother type of the creepystalkerweirdo, the creepystalker is on his way to becoming the former but unable to stalk at a weirdo level. Some might say the difference is that the creepystalker hasn't gone through the full metamorphosis but surely will some day soon. The creepystalker will stalk in a creepy manor but isn't yet as awkward as the creepystalkerweirdo butterfly he will become.
Oh wow, that kid followed me 5 blocks already, what a creepystalker.
That creepystalker is just like his older brother, the creepystalkerweirdo, strange.
