The Panda Express is a risque sexual maneuver in which the male places rice and noodles from panda express in his mouth and proceeds to splooge all over his partners breasts. Next he spits up his Chinese treat on her creamy chest and the girl squeezes her breasts together and eats his Chinese delight.
Guy- Hey, are you hungry?
Girl- Yeah, I'm starving! I could go for some Panda Express right now!
