The Skittle Bomb, also known as "Retreau" (pronounced "Rétro") in France, is an alcoholic bomb cocktail that takes its name from its Skittles confectionery flavor. The method of preparation is similar to the Jägerbomb. It consists of a shot glass of Cointreau, an orange liqueur, dropped into a glass of an energy drink (usually Red Bull).

In Southeast Asia (especially in Singapore), the Skittle Bomb is also known as the C-Bomb, where the C stands for Cointreau.
