In discussing balloon-ish UI elements, I've described the pointy part as 'points', 'arrows' or 'spikes', and that seems to get the idea across to many people alright... but I find myself falling back on hand gestures to clarify my err... point.
What's the best (or proper?) term/phrase to use to describe this anatomical part?
UPDATE
It appears the consensus is that they are generally referred to as tails.
What I find challenging now is that in contemporary UI's, these 'tails' tend to be much stubbier (and the balloons more rectangular) than their comic-book inspiration (more bunny-tail than cat-tail?). I feel like my days of hand gestures and blithering may not yet be over!
