high schoolerish

saying things or acting in a manner that was acceptable while you were attending high school, but now is not so acceptable.

Anna kept using LOL in her messages and I thought that was so high schoolerish.

High School-itis 

A more severe form of senioritis. The symptoms are quite similar, if not identical to that of senioritis, but instead of affecting someone in their senior year, it affects them throughout their entire time in high school. Lack of finished assignments, not having a backpack, sleeping in class, forgetting to shave, and sarcastic yet humourous comments are common. Afflicted will either be unmotivated but quite intelligent, and manage to pull passing grades out of thin air, or just dont care and end up dropping out.

Man I gots the High School-itis, i never do anything
