The last portion of a marijuana bowl to be smoked, which is often a smaller portion and of poorer quality than usual.
I don't want to smoke that, it's a Dave Hit.

When somebody takes a bong hit that is really quick and still gets a ton of smoke. Usually performed by ripping the bong extremely hard but only for a second and a half.
Joe just took a dave hit off that Sour Diesel with that sweet bong.
