A derogatory term used to describe an environmentalist. Anti-whaling is a subset of the environmentalism movement. Describing environmentalists as "whale humpers" mocks the environmental message while demonstrating a deliberate refusal to understand even the most fundamentals elements of that message.
Environmentalist: Excuse me sir, do you have a moment to talk about global warming?
You: get lost, whale humper.
You: get lost, whale humper.

An individual who is so worried about the whales bumping into one another while they are swiming around because the Navy uses sonar to protect there vessel's from combatin enemies that want to kill us.
My friend is such a whale humper she was all happy when the word came down that the Navy can't use an extreme amount of sonar to protect the U.S.A. and their Vessel's because Shamo and flipper bumped into a submarines propellar and they were chopped up into tuna fish.
