sleeper cell

this happens when you stay the night at someone's house, and the next morning while in the shower; you accidently cum on the louffa hanging from the faucet.

Sleeper Ring

This type of ring is made of sterling silver or metal. Worn for one purpose only, to knock people out. Normally worn on the middle finger of both hands.

Brass knuckles are illegal in my state, so I bought a sleeper ring.

Seattle Sleeper

The act of ejaculating onto/into your partners pilliowcase. Then when your partner wakes up the next morning your invisible ink has dried, leaving a white film on the pillowcase.

The reason its the "Seattle" Sleeper is because the city always gets a light dusting of snow that you can only really see in the morning.

I woke up and my partner had left a Seattle Sleeper on my pillow, it took a little more effort than usual to pull my face away.
