Post an alcoholic drink you invented

[NajdorfDefense]

As others have noted, Red Bull doesn't taste very good. At a friend's 5-day bachelor party in Vegas some years ago, we got sick of drinking Red Bull + Belvedere so I thought up the following:

Red Bull + 151 + Creme De Menthe.

Tastes suprisingly good, the CdM masks the Red Bull [after]taste and is good mixed with Bacardi. The girls we had taste-test it with us at Club Ra also enjoyed it, and it certainly has a kick. Needless to say the bartender thought we were insane.

What drinks have you created that range from awesome to average?
