Remember your 21st birthday? Most likely you went to the bar and your friends all bought you shots — probably Redheaded Sluts or Lemon Drops. Maybe if they wanted to test how drunk you were, they served you up a Cement Mixer and laughed as you swallowed the curdled beverage.

Whether you managed to remember your birthday or not, it's safe to bet you've heard the names and probably even tasted a few of the creative shots bars have to offer. Do you know what you're really consuming?

Most people know that a Lemon Drop is part vodka part lemon juice. But, what's in a shot of Liquid Cocaine? It can't really be the narcotic. So what ingredients could warrant that kind of title? Only bartenders and a few savvy drinkers know the answers to these questions, but that's about to change.

FYI: These drinks contain alcohol, so you must be 21 or older to go to the bar, purchase the ingredients and legally consume alcohol.

THE REDHEADED SLUT

Tastes like: You can taste the Jager, but it's fruity too.

Contains:

1 oz. Peach Schnapps

1 oz. Jagermeister

A "jigger" is a double-sided device with a large measure on one end and a smaller measure on the other. The larger measure is usually about 1-1/2 ounces and that is the amount that's called a "jigger." The smaller end is about an ounce, and referred to as a "pony."
