1F

What does 1F stand for?

One female

People may refer to a female who is alone as "1F." The label is used for a woman who is currently alone, whether living in a home by herself or running errands alone in her car.

Where did 1F come from?

At the beginning of 2021, multiple reports emerged from women detailing that they discovered the 1F acronym written outside their homes or on their cars. One woman reported 1F drawn in the snow when she took out her trash, and another discovered it written in the dirt on her car.

Some of these reports were shared on TikTok, a video-sharing social site. TikTokers reacted to the posts by urging them to be careful since 1F is often a term utilized by thieves to mark potential victims vulnerable to attack.

Am I in danger if I see 1F?

You should always be aware of your surroundings, especially if you are a female. But if you do see this mark near your home or car, be careful since you may be a target.

Example

"I was so worried when I found 1F on my car. I immediately rubbed it off but am still shaken."
