The usual term is a "lame duck" president, although this can also be applied to a two term president who's party is voted out of office for the next election - i.e. George H.W. Bush was a "lame duck" president because he only served one term, and George W. Bush was a "lame duck " president because his party lost the next presidential election.
The 22nd constitutional amendment is not a direct cause of Lame-duck presidents. A Lame-duck president will result anytime a new president is elected. The only real impact this amendment has on this occurance is that it guarantees that a lame-duck occurs every 8 years at the latest, as a president cannot be elected to a third term. Before this amendment it was traditional for a president not to seek a third term as President Washington eschewed a third term. Franklin Roosevelt was the only president to be elected to a third term, or a fourth term for that matter, the amendment was a reaction to the length of his presidency. Thus, before this amendment, lame-duck presidents were already occurring regularly and are not the result of this amendment. Hope that helps.
