Get a tall glass, add ice, a jigger of rum (I'm a lush, so make it 2), a jigger of the "simple mint syrup", and top off with limeade. Give a little shake if you're so inclined and top with a fresh sprig of mint to impress your friends. The Mojito in all it's sweet, nummy glory.
And the good part? The mint makes your breath taste good, so when you wake up sprawled on the lawn, clothes askew, and birds building nests in your hair, you can say "Hi" to the responsible neighbor taking a jog and give them a whiff of minty fresh goodness.
Now, get to drinkin'!
(PS: that syrup and a glass of crushed ice and whiskey is a mint julep, if you want to ruin a perfectly good glass of whiskey.)
