chip chat
The annoying chatter that annoying coworkers have with other annoying coworkers about inane subjects, like chips or popcorn.
I was unable to concentrate on my solitaire game because Locquecia was chipchatting with her girlfriend over the phone.
chip and chat
In a crowded bar, when a guy wants to meet and chat with an attractive women, he will bump into the targeted female with a glass of beer near his mouth. Then, he will act as if he has chipped his tooth as a result of the bump, and the targeted female will be concerned and hopefully a chat and hook up will ensue.
Joe is an expert on the "Chip and chat". Thats how he met Jenna at Billys Pub.
