A girl who has features very similar to both a frog and an ostrich. For instance, a girl might have a face shaped like an ostrich but with an wide mouth, a long neck, and then a fat ass stomach resembling the swollen belly of a frog, followed by long ostrich-looking legs.
Note: A frostrich tends to be very hungry all the time and may unexpectedly blurt out a "RIBBIT" periodically.
I wonder if the Twinky-fucking frostrich is going to be home any time soon.
