When having intercourse, flippin' the omelet describes the act of moving behind a woman in order to pursue (takin' the toast).
"Oh. Bro, like during breakfast, dude, I had the toaster all worked out, and i was gonna take the toast, so I was all flippin' the omelet, right? Tryin' to get that booty bounce?"
When you crack an egg in a girls ass, then fuck her until it scrambles. After the eggs are scrambled, the girl tips the eggs in a hot pan and the omelet is made. Served best with hot coffee and fresh fruit.
Hey Tom, how was your morning?
It was amazing! I did anal with my wife and had the morning omelet!
