What term refers to playful conversation or teasing?

The term "banter" refers to a lighthearted and playful exchange of teasing remarks or witty conversation. This type of communication often involves joking or playful teasing among friends or acquaintances, where the intention is to entertain rather than offend. It fosters a friendly atmosphere and can strengthen social bonds through humor.

The other terms do not fit this context. "Barter" relates to the exchange of goods or services without using money, "bizarre" describes something odd or unusual, and "benign" means something gentle or harmless. None of these options convey the notion of playful conversation or teasing the way "banter" does.
