Kissing Teeth

The internet slang term “Kissing Teeth” refers to the act of making a disapproving or dismissive sound by sucking air through your teeth. It is typically used to express frustration, annoyance, or disbelief in a conversation.

Examples:

When someone sends you a message saying they forgot to do something important, you might respond with “Kissing teeth. How could you forget again?”
If someone shares a ridiculous conspiracy theory with you, you could reply with “Kissing teeth. That’s the most absurd thing I’ve ever heard.”
