When someone spews in your martini, changing its texture, color and most importantly, drinkability. See also synonym - chundertini
As first written in the novel Wedding Chronicles by Bob N. Boguslavski

Suddenly, Horace sat up ramrod straight and stiffened with alarmed eyes. A spout
of spew erupted from deep in his throat, cascading over the table in front of him
and sideways as he instinctively turned his head, right into Little Timmy’s adjacent
martini glass.

"Ewwww!" winced Little Timmy, looking morosely at his newly infused cocktail.

This was a reddish pink chunkitini.
