Occurs when a woman is performing MATM (messy ass to mouth) and is so disgusted that she pukes on the man's dick. The resulting mix of shit, puke and semen, typically covering the man's dick, is called a Pinette Scramble.
He jammed his dick down her throat at the moment of climax. His shit covered cock was too much for her. She barfed on his cock resulting in quite a Pinette Scramble. Of course he used her hair to clean up.
