A pillow placed in between two people who sleep together. The pillow is used as a sound barrier for nightime noise; snoring or talking in your sleep. Also used as a signal to bed partner that you are annoyed or pissed off, yet want to stay in the comfy bed!
Dee pillow blocked bad ass so I could get some sleep.
