A Jimothy is any person who has an 8 year-old haircut plus enjoys and/or completes a narrow range of tasks. Namely: burn seshes and paying for YOUR benefit. At said burn seshes he goes nuts and this is where jimothies who have not been discovered show their true colors. They will poor gasoline on things that don't have any business being burned. Second, a Jimothy ALWAYS pays for things. Namely: food, vacations, mortgages, and college tuition. In the end we all love a Jimothy and will always appreciate their presence.

You know you can count on a friend whose name is Jimothy, at least for something.
