Sexburst 

When you eat all 4 of the original Starburst flavors at one time. It is amazing tasting and taste as if your taste buds are having an orgasm. Also due to the large wad of starburst, whenever you talk spit flies out of your mouth, as if your mouth is cumming. Completely Amazing

Ahh, the Sexburst was the most amazing thing I have ever expirienced.
