We introduce a very simple and exactly solvable model that supports Fermi arcs in its ground state and excitation spectrum. These arcs come in pairs, and merge into what we call a pseudo-Fermi surface along which fermions are gapped; this fermion gap is naturally identified as a pseudogap. A comparison will be made with the phenomenology of high-temperature cuprate superconductors.
