Definitions for "Valsalva"
The act of pinching shut (with thumb and forefinger) a woman's nose while receiving fellatio; most effective when employed just prior to the release point due to the gag reflex and ensuing swallow that the woman is forced to do to continue breathing. A great first date ploy, as it sets the stage for what the rules of engagement will be going forward.
