The sound a mobile phone makes while ringing when it has been set to vibrate. An unintentional side effect of not taking the phone out of silent mode, it's reminiscent of the "mmm-mmm-mmm" sound a bound and gagged hostage makes in a movie when trying to get attention from a rescue squad.
Dude, your phone has been ringing nonstop - doing the hostage on the table while you were off dropping that deuce.
