Cut up mangos and place in a blender. Pour as much mango rum (i recommend anything stronger than malibu) as you can handle into the blender (note: the mangos will take off most of the alcohol bite.) Next, pour the citrus soda (mountain dew/mello yello/sprite) in the blender to sweeten it a little. Add ice and blend. You can pretty make your drink pretty by drizzling a little strawberry syrup in the bottom of the cup and on top of the drink! This is a drink that you could use a whole bottle of rum and still think you're drinking a smoothie... but trust me... you'll feel it!!
