"Mugs."

"Doves."

"Gluten-free cupcakes."

So Ben Platt and Skylar Astin suggested as titles for their characters' signature songs in the "Pitch Perfect" franchise, a la Anna Kendrick's "Cups" in the original "Pitch Perfect."

In "Pitch Perfect 2," cast newcomer Hailee Steinfeld rocks her original song, "Flashlight," throughout the film. Of course, with the emergence of "Cups" and "Flashlight" both, we were dying to know what songs the rest of the cast would take as their trademark. Platt and Astin were kind enough to ad-lib the lyrics to their original song, about gluten-free baked goods (natch), and Rebel Wilson and Adam DeVine, who return as will-they-won't-they duo Fat Amy and Bumper, showed off their (literal) harmony as a pair.

Check out the clip above to find out what the rest of the cast chose as their signature tune.

"Pitch Perfect 2" hits theaters May 15.
