I used to bartend, AND everywhere I have ever been a Liquid Cocaine shot is this:
151
Jager
Rumpelmintze
Goldschlager.
Hootie, be careful ordering those, when yu're out of your hometown. You might get something unexpected
I love them, but they'll F*** you Up!
Also, another fave shot of mine is a Minderaser.
its more of a shooter, 1 ounce Kahlua 4 ox vodka, insert straw and suck. very fast. very fast.
