Two people must be engaging in oral sex. Whoever is receiving the deed must act swiftly and shove the givers head down towards the anal cavity. The receiver will then proceed to drop ass in the givers face, resulting in him or her getting pink eye. (for extra pleasure, foreshadowing the event, hum the pink panther tune prior to the dropping of ass)
Hey did you see Jenny got pink eye? I gave her the pink panther last week.
