Thank you slap

The slap someone deserves when they're trying to help but making things worse.

Shawna: "Hey everyone! Bella is single now, so she's dating again if you're interested!"
Bella : "Shawna! What are you doing?!"
Shawna: "I'm helping you out, girl!"
Bella: "Oh. You're so kind, I think you deserve a thank you slap!"
