Can someone tell me what the real "dim lo" is, because one of the people who answered said its somehting else?

There is a person who answered one of my other questions, and I would like him to answer this one. Like I said before, I thought this "dim lo" technique was a move to immobilize an attacker, but the answer was that the "dim lo" he knows of is nothing like I described, grabbing a persons arm, twisting it up their back, and grabbing them by the neck while throwing them to the floor. I would like to know what the "dim lo" that the person knows of is, I'm interested to hear what is really is? Thanks.
