The MMR on lolking is only an approximation of your real MMR, and they refer to it as lolking score. In this case, yours is 1150, and is found to the right of your name above your division icon. For a more accurate reading of your MMR, i reccommend this website: http://op.gg/mmr/region=NA
To get an accurate reading, make sure at least half of your previous 10 games have been in ranked.

The "MMR" they're talking about would be the LKS, that is, the LoLKing score. The 1150, that is. As for whether it is legit or not, I doubt it.
http://op.gg/mmr/region=NA is another website you can check. When you're in a game, http://quickfind.kassad.in and search your name. It should have something like, "Hidden Elo Average: ****" That is the average of the game. The "MMR/Elo" on your team's title thing is the average of your team.
And of course, the legit-ness of these websites are unknown. So it may or may not be your actual MMR.
