  Large azimuthal quadrupole and octupole asymmetries have recently been found
in p+Pb collisions at the LHC. We argue that these might arise from a
projectile dipole scattering off fluctuations in the target with a size on the
order of the dipole. In a holographic scenario, parity even angular moments
$v_{2n}$ are generated by the real part of the light-like Wilson loop due to
the contribution from the background metric to the Nambu-Goto action. On the
other hand, parity odd moments $v_{2n+1}$ must arise from the imaginary part of
the light-like Wilson loop, which is naturally induced by a fluctuating
Neveu-Schwarz 2-form.
