  The repeating FRB 121102, the only FRB with an accurately determined
position, is associated with a variable persistent radio source consistent with
a low luminosity active galactic nucleus. I suggest that FRB originate in the
accretion disc funnels of intermediate mass black holes. Narrowly collimated
radiation is emitted along the wandering instantaneous angular momentum axis of
accreted matter. We observe this emission as a fast radio burst when it sweeps
across the direction to the observer. This model constrains the mass of the
black hole to values below those of galactic nuclei. It predicts, in contrast
to neutron star (pulsar or SGR) models, that repeating FRB will not be periodic
and will be co-located with persistent but variable radio sources resulting
from the off-axis emission. The model is analogous, on smaller spatial, lower
mass and accretion rate and shorter temporal scales, to AGN making double radio
sources, with FRB corresponding to blazars in which the jets point toward us.
