Holiday Hijacker

(Noun) a person who thinks it is acceptable to schedule their stupid life event (wedding, baby shower, etc.) on holiday weekends, thus putting you in a socially precarious spot of forfeiting your free time or telling them they're not worth a long weekend.

Me: I wish I could but Ellen is a holiday hijacker and scheduled her stupid wedding for that weekend.
Friend: Bitch.....
