"Plants & animals disappear to make room for your fat ass" is the phrase for this bumper sticker. To be honest, I don't quite get the message bumper sticker is meant to convey in this context. The phrase can't be an anti-car message -- otherwise the "fat ass" could end up being self-referential. Is the sentence an anti-SUV message, in which case the "fat ass" is that of big cars? Maybe the driver is really thin, so possibly fewer plants and animals died for the driver's thin ass.
Anyone help me understand this?
