A recent high school grad that refuses to move on with his life and goes to high school parties and hangouts in attempt to relive his senior year. Usually to the chagrin of the actual seniors trying to enjoy it themselves.
Elliot is such a fifth year senior, he needs to get a life and quit hanging out at high school parties.

Someone who it takes 7 years or more to finish their undergraduate degree, meaning they have been a senior for a long ass time. A seven-year senior in most cases has gone to college part time, full time, taken time off, etc.
