Self boosting

Someone who thinks that they're unbearable to be around, even though those that have been around them have born their presence as long as they've known the person. Usually females think this way.

A female who thinks every male she knows should consider her presence unbearable has a self boosting and entitled attitude, as much as any male she's claimed had one, period.
