This is someone who has sexual encounters in no other location other than kitchens. Often times they are wearing a giant egg costume (like that over easy omelet costumes on Halloween), while the other person is wearing a bacon costume. It does not matter what sex is wearing what costume, however. When they want to "spice it up" one wears a tabasco costume. Another version of kitchen sleeper can be seen in the image.
"Jack and Jill were kitchen sleepers, and they tried to get me to spice it up, but I didn't have the costume."
