Brown Sunrise 

n. The act of defecating in a partner's nose. A variant on the Cleveland Steamer. So named because, like a beautiful sunrise, the recipient will smell shit every morning for a month.

Linda never forgot Barry; though they'd broken up years ago, she still remembered the Brown Sunrise he gave her as an anniversary present.
