  We present a gravity dual to a quantum material with tilted Dirac cone in 2+1
dimensional spacetime. In this many-body system the electronics degrees of
freedom are strongly-coupled, constitute a Dirac fluid and admit an effective
hydrodynamic description. The holographic techniques are applied to compute the
thermodynamic variables and hydrodynamic transports of a fluid on the boundary
of an asymptotically anti de Sitter spacetime with a boosted black hole in the
bulk. We find that these materials exhibit deviations from the normal Dirac
fluid which rely on the tilt of the Dirac cone. In particular, the shear
viscosity to entropy density ratio is reduced and the KSS bound is violated in
this system. This prediction can be experimentally verified in two-dimensional
quantum materials ({\it e.g.} organic $\alpha$-({BEDT}-{TTF})$_2$I$_3$ and
$8Pmmn$ borophene) with tilted Dirac cone.
