Talking a lot, usually in a continuous or gossipy way; chatting without a serious purpose.
From Middle English 'gabbe' (to mock or scoff), possibly from Old Norse 'gabb' (scoff). The sense evolved to mean prolonged talking, with 'gabbing' becoming the gerund form emphasizing continuous chatter.
Every language has specific words for meaningless talk—English has 'gabbing,' 'yammering,' 'prattling,' 'nattering'—and these words reveal cultural attitudes about conversation. Many of these words are slightly dismissive, suggesting that people should be more direct and purposeful in speech, yet humans actually spend enormous amounts of time in 'gabbing,' which serves the important social function of bonding.
