Humans are naturally drawn to exclusivity. Being addressed by someone who acts like they are "above" everyone else creates a unique form of parasocial interaction.
"We’re actually waiting for someone who... well, someone who fits the table. No offense. It’s just a vibe thing. You look like you’re about to ask for a selfie or a favor, and I’m really not in the mood for either today."
Mean bitches are often intelligent, charismatic, and calculating. They know exactly how to work a room, how to read people, and how to get what they want. They're not afraid to use their charm and beauty to manipulate others, often leaving a trail of broken relationships and hurt feelings in their wake.
