Definitions for "swirling"
A sound heard on a digital call which indicates that the phone is trying to make speech sounds out of background noise. Often reducing the phone volume or moving away from open windows and air vents can minimize this sound.
The act of sloshing the wineglass, with wine in it, around in small circles, the aim of which is to expose as much of the wine to air as possible without splashing it on your frock. Speaking technically, Swirling stirs up all the smellies in the liquid until they get so excited they have to leap into the air above the wine, where your nose can easily capture them. Warning: don't try this with a full wineglass--this is why winegeeks favor pours of a few ounces at most if they're in full-on geek mode.
moving or driven rapidly in a rotary or twisting motion; "a tornado's whirling winds"; "swirling currents"
