What do you call that Thing?

I have heard this word before. I don't admit using this word ever. But I have never seen it written anywhere. Who would write it? Why would they think it worthy of space on a page? Only in a dictionary of Spanish translations to English...in Uruguay. The Spanish word is "Chisme" meaning gossip, but apparently some other things as well. Look at one of the words used in the dictionary here to define it.
