Googling for Definite Majority Choice takes you here:

     http://wiki.electorama.com/wiki/Definite_Majority_Choice

Here is a summary, stripped of extra terminology:

,----
| - Ordinal ballot with approval cutoff.
| 
|   * For example, each slate of candidates could have an extra
|     fictional candidate, "Not Approved".
| 
|     The approval score is the number of votes FOR a candidate
|     AGAINST Not-Approved.
| 
| - Eliminate candidates who are defeated one-to-one by any other
|   higher-approved candidate.
| 
| - Among the set of remaining candidates, eliminate any candidate who
|   is defeated by a lower-approved candidate.
`----

In the case of no ties, there is a unique winner.

I won't discuss strategy, but many of the same considerations apply as
in Approval Voting.

I'm leaving my current job on the 31st, and it may be a month or so
before I start again at my new one, so don't expect to hear from me
for a while.
