If you've had her album Prism on repeat since it dropped last fall, you've already heard the bubbly, tongue-in-cheek track about straight stuntin' on the weekend. You know how it goes: getting your nails done "Japoneezy" by day, and partaking in "Mariah Carey-oke" by night. Oh, and if you're not eating breakfast in "last night's dress," you're doing it all wrong.
Will it overthrow Iggy Azalea's "Fancy," as the song of summer? We can't say. But you best believe Perry when she promises it will keep your party trill.
