Short for "Young Urban Marxist". A former marxist who now has a high paying public service job with a great pension plan and full benefits. Like their yuppie counterparts they live in big houses and drive big SUVs while still complaining how the system is still sticking it to the poor.
Yummies try to save the environment by using canvas bags while driving their SUVs to the organic supermarket.
