The best coffee-lime-rum martini you will ever drink

This cocktail comes--with slight modifications--from the wonderful family-run Backwards Distillery in Casper, Wyoming. I have tried their gin and rum, and they are both amazing--the gin is the most interesting I think I have ever tried. I am not a paid advertiser, just a huge fan. So, without further ado...

Buzzed Martini (originally called "The Perky Daiquiri" from Backwards Distilling)

Makes 1 drink

1.5 oz rum (their's is called Sword Swallower  and it's delish)
2 oz cold coffee
1/2 oz lime juice
1/2 oz coconut milk
1/2 oz simple syrup

Shake all that shit up with some ice and pour into a glass. Try not to drink it too fast...
