1. Crack open the bottle of Corona Extra and drop the lemon slice inside.
2. Serve a double-shot of Bacardi Limon with the rim of the shot glass layered with margarita salt.
3. Take the double-shot (holding the double shot in your mouth), and fill the rest of your mouth (with the double shot still inside) with Corona Extra.
4. Have a friend (with the mix of Bacardi and Corona in your mouth) shake your head for a solid 3 seconds, on the count of 3 down the mix in one swallow.
