If all your kids are named after brands of beer, there ain't no might, you are a redneck +50
If your boys are all named after broadheads, you might be a redneck +20
If you have a car sitting in your yard on cement blocks with antlers as the hood ornament, good chance there too buddy. +10

Trouble is, I got a neighbor that #2 and #3 above are true. His baby boy was born last week and is named "Rage"
I also know someone who committed #1 above.
