blumpkinschplatt

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.

The redheaded girl from around the way performed blumpkinschplatts regularly due to her unusual upbringing.
