3.
A pair of gluteal muscles that are so well formed they defy physics (i.e. Nikki Minaj, Jeniifer Lopez, Jasmine Sindo, Vida Guerrera, Coco, etc.) . The most common side effects upon viewing this phenomenon are loss of motor skills and an inability to speak coherently. Effects are quadrupled when the ass in question is sighted in yoga pants. Gaze with caution, sunglasses are recommended.
