Simp Signaling
When a person (usually a female) who is stuck up/snobby is encountered by a person that they don’t want around them for any reason (not attracted to/annoying/etc.) And the person is bothered by them, and she/he begins “Simp Signaling” the nearest Simp closest to them for help, even if their plea for help is unnecessary, and is usually resolves by telling the bothering person to go away, but instead decides to involve a Signaled Simp to resolve the situation with the unwanted person. “Leave her alone man! She doesn’t like you!!.”
The preppy cheerleader chick was Simp Signaling one of the party simps to tell the brave band geek who was indirectly invited to the party to leave her alone, because he tried to flirt with her.
