A character, usually female (ironic as the Trope Namer is male), suspects a male character, often a neighbor, of committing a crime. Perhaps she is even a witness of the crime. Nobody believes her, or she isn't sure herself, so she decides to wait until he leaves his house, and then sneak in to look for clues or to obtain incriminating evidence. Of course, the potential suspect will invariably come home early, and the investigating character will have to find a way out of the house without being discovered. Sometimes they do, sometimes they don't.
This can be an Idiot Plot, because the character in question often fails to be certain that the probable bad guy will actually be gone for a while and is not just getting his mail or something. In some versions, another character will be placed as a lookout, but they will either become distracted and fail to notice the bad guy as he arrives home, or their signal to get out will go unnoticed by the infiltrating character.
There's also a less common but still prevalent comedy version of this trope, where the investigating character is trying to retrieve something, often an embarrassing item they've left behind.

- In Dirk Gently's Holistic Detective Agency, one of the main characters breaks into his girlfriend's house to delete a message from her answering machine (Note: the book being written and set quite a while ago, this means listening to all of her messages, off a series of cassettes, until he finds the one he made). It turns out he's actually possessed by an ancient alien ghost.
- Point Horror novel The Window clearly and deliberately rips off the plot of Rear Window: When a young woman accompanies her friends on a ski trip and ends up spraining her ankle. Stranded in her room and bored, she begins spying on the other cabins with a pair of binoculars. Sure enough, she witnesses a murder and the killer him/herself, though she can't tell who it is—it quickly doubles as a Locked Room Mystery when she realizes it has to be one of the friends she's traveling with—and ends up playing a nail-biting cat-and-mouse game trying to figure out exactly who it is without tipping them off.
- The Seinfeld episode "The Phone Message" revolves around an angry message George left on his date's phone while she was out of town, and his attempts, using Jerry as a decoy, to sneak into her living room and change the cassette before she hears it.

The sheer number of times he has snuck into someone's property means that, statistically, he should still be paying fines/jailtime for breaking and entering in 2099.
- In a Halloween episode of That '70s Show, Fez breaks his leg and stays in Eric's room, watching the Pinciotti's house and hoping to see Midge, their MILFy next door neighbor, naked.
