  In the context of Twin Higgs models, we study a simple mechanism that
simultaneously generates asymmetries in the dark and visible sector through the
out-of-equilibrium decay of a TeV scale particle charged under a combination of
baryon and twin baryon number. We predict the dark matter to be a 5 GeV twin
baryon, which is easy to achieve because of the similarity between the two
confinement scales. Dark matter is metastable and can decay to three quarks,
yielding indirect detection signatures. The mechanism requires the introduction
of a new colored particle, typically within the reach of the LHC, of which we
study the rich collider phenomenology, including prompt and displaced dijets,
multi-jets, monojets and monotops.
