spit-take
n.— «Yet, “after all I’ve done, what I’m most remembered for is the spit- take.” That’s the point in Make Room for Daddy when [Danny] Thomas would be sipping coffee, somebody would say something surprising, and he would spit it out.» —“Thomas makes room in his schedule for ‘Nest’” by Jefferson Graham in Beverly Hills, California USA Today Feb. 1, 1991.
