When you’re excessively going far back into someone’s social media past, and cannot afford to be caught out (e.g- accidentally liking a photo)
Omg I’m 85 weeks back into Jonathan’s Instagram...I’m so deep in the creep right now! I better not like anything!!

Using a cloaked and/or fake Facebook account to spy on people you know, often while claiming that you do not use Facebook.
That sick jerk I have a restraining order against just got caught book creeping all over my Facebook page.
I've got a little book creeping to do right now but when I'm done I can teach you how I use roofies

I didn't sleep well due to sheet creep. When I woke this morning my bottom sheet was partially on the floor and I was laying on a bare mattress.

A phone that an unfaithful man would use just for other girls that he's seeing on the side
The mans second phone that he should keep hidden from his girlfriend/wife/w.e

The role needed to be adopted when trying to find a car parking spot in a shopping centre. Being a carpark creep involves adopting a motivated attitude immediately after entering the carpark. The carpark creep identifies a pedestrian and follows the pedestrian to their car, almost catching the back of their shoes from driving so close to them. Best done in a Prius as they are very quiet cars. The carpark creep has no shame.
Mum: "I don't have time to waste looking for a car parking spot so I have no choice to be a carpark creep."
Kid: "But Mum.... This is soooooo embarrassing!"
Mum: Tough luck kid, you ain't driving the car so you need to deal with it.

When you have a long term girlfriend, but your out on a secret date with another woman, your creeping already, but you notice a girl while out on your secret date, and you do a number grab as she's at the bar, hopefully without your secret date noticing, you just preformed a double creep!
"was partying with a slut while the missus thought I was out with the lads, even managed to bag a number off another honey while said slut weren't looking, perfect double creep it was"

when someone takes naked pictures of the person they hooked up with that night while they are asleep and then shows all their friends the pictures and gives each other high fives
The Sleep Creep stealthily waits while his unsuspecting drunk partner falls asleep after orgasmic bliss only to be struck upon by the infamous Sleep Creep. The Sleep Creep takes photos of any exposed body part to keep as a trophy and memento to show all of his fellow Sleep Creepers. All the Sleep Creeps then have a round of laughs the next day over a round of drinks and plot for their next night of Sleep Creeping. The photos are not posted on the internet...that is just mean and could get you in trouble! ;-D
