Irene needs to talk to Alice and Bob. She goes to Bob's room, opens the door and sees Alice and Bob in a compromising position. "Ok," Irene thinks, "just slowly back out of the room and close the door."
This trope is when someone opens a door, sees something unexpected, and does an about face. They may mutter something like, "I'll come back later," "You seem busy," or "Sorry to interrupt." Now what the people in the room are doing may be Not What It Looks Like, and often isn't even sexual at all. The two people may be summoning a ghost, or conversing with their toys. On the other hand, this covers solo acts.
Afterward, outside the door, the interrupter may start ranting, screaming or searching for Brain Bleach.
A common variation is to play the scene from the other side of the door. Albert and Brenda are doing something innocent, and just at the wrong moment, someone opens the door. As per Finagle's Law, they're invariably caught when the potential for Not What It Looks Like is at its highest.
Especially embarrassing when the person accidentally interrupting had previously been purposefully sent away. Or in...certain other situations. If shown from the perspective of the couple interrupted, see Interrupted Intimacy.
Related tropes include Backing Away Slowly, which is a slightly different take of getting away from an awkward situation, and Screw This, I'm Outta Here, when a character walks away from an uncomfortable situation happening around or involving them rather than one they just walked into.
