When you're wearing loose boxers and your penis slides out to the side, next to your thigh.
"Hey man, you finished with the shower? Don't worry, I've got my boxers on"
"Oh Damn. Someone's got a peeker."
When a female can sense people/someone staring at her bum as she walks or leaves a room
“Zac is such a peeker i knew he was staring at my bum when i left the room”
The sensation when you have to poop and the turd is peeking out of your asshole.
I have to find a bathroom quick, I've got a peeker!
That one random kid that stares and watches.....
The peeker-. . . . .
That one girl-Who is that?
Where a strange man comes into your house peeks at your butthole to see if your clean/have wiped thoroughly.
I heard that Hudson Frensley got peeked by the butthole peeker, hopefully he won't peek me!
