The act of holding a dick in ones mouth while the person sits on their shoulders. By sitting on the others shoulders and inserting their dick in the others mouth, it forms a "lock" between the two people for stability or other needed reasons.
I couldn't reach the jar on the top shelf so my girlfriend let me sit on her shoulders, then she let me lock-up so I didn't fall.

Locked Up is when you run upstairs to talk to your parents and the door is locked. That would be considered Locked Out, but in Locked Up, its when the door is locked because your parents are having intercourse. Of course you would not know this unless you could hear the sex noises. Hopfully you can not.
I ran up to my parents room, it was locked. I then put my ear to the door, thats when i noticed i was locked up.
