Fuelivore 

An excessively large SUV or truck that guzzles fuel and will ultimately bring about the destruction of all life on Earth as we know it.

Chip: Hey Waldo, did you just see that Hummer ram that Geo off the road?

Waldo: Yeah, Chip. I can’t stand those fuelivores who throw their weight around the streets like Rush Limbaugh at a Krispy Kreme. Hey, is it just me or does it seem unseasonably hot this winter?

femivore 

Women who have veered from the work force into raising chickens, growing vegetables, and canning. A DYI locavore

My femivore friends may never do more than dabble in backyard farming - keeping a couple of chickens, some rabbits, maybe a beehive or two - but they're still transforming the definition of homemaker.
