According to MSU fans/students, you're a "Walverine" if you fall under any one of the following categories:
1.) You are not from Michigan.
2.) You are from Michigan and have never attended college.
3.) You have attended college, but not at the University of Michigan.
4.) You have family members who went there, but you did not attend.
5.) You are a student as either an undergrad or grad at either one of U of M's two satellite campuses (Flint or Dearborn).
6.) You are an undergraduate student at U of M's main campus in Ann Arbor, but enrolled in something they deem "too easy" like LSA or Art.
7.) You are a graduate student, but not studying Engineering, Medicine, Law, etc.
8.) You're breathing and wearing the color blue.
