When you are locked out of your own room by someone who is making an attempt to get laid. This person usually will not let you in the room no matter the circumstances.
Man, That Mike is such a door locker. I had to sleep out in the hallway, and he didn't even get laid!

The same as a door locker, but used when the door has an automatic lock like a hotel door, or cruise ship cabin. The bolt is used in addition to the automatic lock.
Fuckin' Mike is such a Double Door Locker. He locked me out of my own cabin, and I had to sleep in the hallway.
