To a large pitcher, add spiced rum, coconut rum, pineapple juice and lime juice. Stir to combine.
To a small plate, add a drizzle of light corn syrup. To a second small plate, add various sugars (I did a combination of white, green and blue). Dip rims of glasses in corn syrup, then in the sugars to coat the rim.
Fill serving glasses with ice cubes and a few lime slices, add a splash of blue curacao to the bottom of the glass. Top with rum mixture and garnish glasses with a slice of lime.
Notes
If you're not a huge fan of pineapple juice, replace 12 oz of the pineapple juice with 12 oz of lemonade. You can also top off the glasses with a bit of club soda or lemon lime soda for a bubbly drink.
