How to make the Blacktooth Grin – This drink was invented by the guitarist Dimebag Darrell of Pantera and Damageplan. The ingredient amounts are not exact for this drink. The general idea is that you have half and half Crown Royal® and Seagram’s 7, and just enough Coke to darken the color of the drink. The name of this drink comes from a lyric in a Megadeth song called . Sweating Bullets. “. RIP Dimebag Darrell. First pour in the shot of Crown Royal® and add approx. half shot of Coke. Then pour the shot of Seagram’s 7 plus the rest of the Coke. Serve chilled or over Ice. Enjoy!”
