When you go down on a girl when she's on her period.

The female period blood is representative of salsa, a typical dish with Latin origins which is included in omelettes in that culture. The omelette is of course the eggs from the ovaries that are flushed out of the vaginal canal during shark week (the only decent thing the discovery channel has done in years)
"Yo, Jeff, you go down on your girl last night?"
"Yeah, but she was in the middle of her shark week so I gave her a Mexican omelette."
