The act of leaving a surprise poopie on the adjacent pillow of your one night stand, so that they may roll over onto it or wake up next to it, and you are gone.
Example 1: After very bad sex last night, Bryan decided to leave his one night stand a morning bun.

Example 2: Chelsea was rudely awaken after her face rolled over onto the the morning bun left on her pillow, by the guy she had met the previous night.
