look up any word, like bae:
 
1.
Noun. Somebody who is a cross between a creep and a pervert. These people are usually seen walking around with their shoulders slightly raised and their eyebrows slightly lowered. Usually accompanied with a pedosmile. To be a true creepert, the person would lurk around their prey - stalkerishly - and then say or do something dirty when recognized.
"Joe is such a creepert. Yesterday he followed me home - staying back a ways. When he saw me about to go into my house he ran up to me, pedosmiled, then said 'nice tits'"
