Icarly-Syndrome
When a girl (or man/non-binary) has a person simping for them, only to reject them for a period of time and then get upset when their ego booster wants to get into a relationship with someone else who isn't them (despite them showing disinterest in the first place). This is behavior the protagonist of Icarly showcased towards a male character.
"Hailey's upset I wanna date Cassandra even though she's been rejecting me for the past month or so."
"She has Icarly-Syndrome. Don't worry about it."
"She has Icarly-Syndrome. Don't worry about it."
