A person who has a Lack of Personality who has no sense of humor no common sense , who is dull , boring and has no clue about what to do or how to act.
You could tell he was a L.O.P by the way he acted.
Left Over Period
When you finger a girl right after her period and you find L.O.P stuck under your fingernails.
Tony had a really good weekend until he got up with Suzy and ended with L.O.P on his fingers.
Loyalty Over Pride. Representing GD is a gang that works as GD. These people are badass and aren't recommended to mess with. They are often calm and peaceful. Press their buttons and they'll press that trigger. There isn't much to be found about this gang because they are stealthy and like to stay under the radar in person. You can't just claim to be one, you have to atleast talk to @maukworld to even get started in Initiation. If you don't get initiated then you aren't in.
"What are you in?"
"I'm in L.O.P GD"
