Battlefield 3 - How to get Nemesis Ribbon

Some people find it is difficult to get the Nemesis ribbon in battlefield 3. The reason for this is many of them are not sure how to get this. In battlelog it says 'Get 2 Nemesis Kills'. What does that mean?

IN BF3, You become someone's nemesis, if you Kill that player 5 times, without him killing you in between. The other players can still kill you. Once you do that, you become that person's Nemesis.

I have searched the net to find out how to get the ribbon. There are two solutions.

1. Become a Nemesis twice.(Confirmed) ref: http://battlelog.battlefield.com/bf3/battlereport/show/28140831/2/224752992/
   - Kill two players 5 times each without them killing you
   - Or Kill the same player 2*5 times. (you can get killed after the 5th kill and this will still get the ribbon)

2. Kill 2 of your Nemesis (Not confirmed)
  - Get killed by the same person 5 times. Then kill him - do this twice (your nemesis can be two different palyers or the same player).
 - TIP: try to get into matches with low player count to increase the odds. Try Squad Daethmatch
