A symptom that seniors in high school usually have. It causes them to not try hard in school, skip class and go to the beach as well as think they are better than all of the underclass men. All they are looking toward to is graduation and to finally be in college.
Senior 1 "Should we go to school today?"
Senior 2 "No, I mean we're seniors so let's just skip and we'll go to the beach"
Senior 1 "That sounds like a better idea, besides we're graduating in 5 months"
Senior 2 "Haha, we have a bad case of senioritis"
