  We study a mechanism where the dark matter number density today arises from
asymmetries generated in the dark sector in the early universe, even though
total dark matter number remains zero throughout the history of the universe.
The dark matter population today can be completely symmetric, with annihilation
rates above those expected from thermal WIMPs. We give a simple example of this
mechanism using a benchmark model of flavored dark matter. We discuss the
experimental signatures of this setup, which arise mainly from the sector that
annihilates the symmetric component of dark matter.
