From the word 'dissident' and the corporation '
Disney', this term denotes a person who is involved in a boycott of
Disney and all Disney affiliates. Much
like a vegetarian, this person will probably believe themselves to be morally superior, and try to force their beliefs on you whenever possible.

Tom: .....oh.
