Stands for Lying Obsessive Compulsive Disorder. Not a real disease of course, but the difiniton is:
A person who tells many lies and they think they are getting away with it.
When people start to ask questions, they make up more and more lies to cover up, then there is a whole big web of lies. A person with LOCD doesn't know they have LOCD.

Emily: Yeah when i asked her what movie she saw she said that she "forgot"
Kate: haha, i think she has developed LOCD
