Histrionic

/ˌhɪs.triˈɒn.ɪk/ adjective hard

Overly theatrical or dramatic in a way that seems exaggerated and insincere.

Her histrionic reaction to the minor inconvenience made the whole office stop and stare.

Memory Trick

The word comes from the Latin term for actor — a histrionic person behaves as though performing a dramatic scene on stage rather than simply living real life.
