That one friend that always makes terrible schemes,that are so stupid that you want to join. They are extremely nice but they are also retarded. They trust to easily, and their heart breaks fast. This is the type of friend you need around you at all times.

However, they are highly protective and stand next to what they believe even if its retarded.
