A sexual act in which during the final moments of sexual intercourse, a male proceeds to ejaculate onto his female partners face, and in the process of doing so, simultaneously claps his partners ears with both of his hands in a single motion. Said motion results in the rupturing of the partners ear drums. The partner then, writhing in pain, begins to cry and mascara runs down her face. The culmination of the recipients dark, running makeup, ejaculate covered facial region, and fruitless attempt at holding her ears to alleviate the agony, all result in the physical resemblance of the Giant Panda (Ailuropoda melanoleuca).

Friend 2: "But I'd do it again in a heartbeat..."
