Bi?

When I was a CP I had a duty for a little while making sure that the school mini busses were kept clean.

But what is the plural of bus? The Master i/c in those days said that it should not be busses.

His logic was impeccable. 'Bus is a contraction of Omnibus. The plural of omnibus would be omnibi. The Plural of minibus should therefore be minibi and the plural of 'bus? 'Bi.
