A blumpkinschplatt is considered achieved when a girl vomits as a reaction to male orgasm whilest the male is seated on a toilet, shitting.
Note the
difference between this act and a regular blumpkin. A blumpkin could be considered performed when a girl quickly puts her tounge
on the tip, whereas a blumpkinschplatt is proof of it's own
sexual satisfaction. Blumpkinschplatt is visceral and undoubtedly sexual whereas blumpkins are more abstract and humorous.
