From the words of Ryan Higa

In horror movies
If there are signs telling you to GET THE FUCK OUT, GTFO
For example,
If you walk into a room and there is one single light source hanging from a ceiling, you should probably GTFO
If you walk into a room and any of the light sources are flickering, you should probably
GTFO
If you buy a new house for a really good deal and all the other neighbors are scared of you, you should probably
GTFO
If you see someone in the reflection of a mirror who isn't supposed to be there
GTFO
If you hear the previous owner was murdered in your house
If you ever see anyone in your house that's not supposed to be there
If you have a kid that knows how to astroproject
If you have no cell phone service
If its always storming
If there's a sign that says Beware
If there's a sign that says Keep Out
And if there is literally a sign that says GTFO....get it because I would really like to have that sign that's really cool
