When, after having several men ejaculate into a woman's/man's asshole, she/he then proceeds to fart the contents of the anal orifice onto an individual's face or object. Thus the term, 'Bukkake Thunderclap".
"Dude, did you see that video where 15 guys came in her asshole? She then bukkake thunderclapped on the camera!"
