Literally meaning "son of James". Though originally a surname from Scotland and Ireland, Jamison is also used as a first name by parents who fear the name "James Jr." will doom their child to a career as a mechanic or garbage man (as is the fate of most "Juniors".) All men named Jamison have been found to be highly intelligent, funny, charming, classy, gorgeous and sexy as hell. Unfortunately they also have a mean streak and one should fear for their lives if they acquire any enemies named Jamison. He will kill you and bury you in the woods...then go screw your girlfriend.
Jamison is amazing. Enough said.
