  The universe's current acceleration is a pretty recent phenomenon in
cosmological time scales. This means that the modes that have left our horizon
since the beginning of the contemporary acceleration phase, have not really
reached the exact IR limit. Noting this observation, we reconsider the
possibility of having a ghost condensate as dark energy with a sixth-order
dispersion relation. Looking at the three-point function of such a theory, we
obtain the constraints on the coefficient of the sixth-order dispersion
relation to avoid strong coupling. Such a ghost condensate if coupled to the
standard model fields, induces a constant Lorentz-violating spin-dependent
force, which can gravitate or anti-gravitate.
