A bizzare expression used by some people to describe the small, square cushions placed on a couch to enhance it's comfort and aesthetics, as opposed to the larger cushions which form the seat and are hence integral to the couch.

They're not "couch pillows", they're CUSHIONS. Pillows are what you rest your head on while you sleep, cry into when you're a teenage girl or bite when you get fucked in the ass - but only when the aforementioned events happen IN BED.
From Step Brothers (2008):

Richard Jenkins: "Dale sleepwalks too."
Mary Steenburgen: "Are you kidding me?"
Richard Jenkins: "I'm not. Look in the oven."
Mary Steenburgen: "What's in the...couch pillows?"
