TikTok has officially named October 1st an unofficial holiday celebrating love, relationships and the arrival of fall. The trend, which has won the hearts of millions, is not new, but has resurfaced this year. Although its origins remain unknown, the trend revolves around Girl In Red’s song, We fell in love in October.

In the song, the artist sings about falling in love with a girl and having a relationship with her. The song has since become popular not only in the LGBTQ+ community, but in all types of relationships.

While the trend may have been an initial hit in the WMW community, it has since become the go-to for couples of all kinds. Men use it for their girlfriends, fathers for their daughters, and so on. And so on October 1, everyone takes the stage to celebrate their loved ones. The lines that appear most often in TikTok videos are:

“You look so beautiful and I love this view / We fell in love in October / That’s why I love autumn,” and “My girl, my girl, my girl / You’ll be my girl.”

It is striking that the trend is not limited to couples. Singles also share their thoughts on the audio clip, wishing they had someone just in time for the official-unofficial holiday. Other people use it to post clips or ideas for a date night they would like to have someday.

Several factors can contribute to the popularity of the holiday, such as the appeal of the approaching season and the fun that comes with it, and more technical reasons, such as social media culture itself and the use of hashtags such as #1October.

Related to, and as if it weren’t enough, February 14, the holiday, is another day to celebrate all things joyful and loving. The trend started in 2023 and it’s safe to say that it has sparked a lot of reactions since then, including memes and jokes.

The trend has generated more than 50.5 million posts on TikTok and more than billions of views. One user on TikTok posted a clip of the audio and the caption read:

“POV: You were watching stories on October 1st” while scrolling through TikTok.”

Another used the same audio for a video that received over a million views:

“I hope I’ll be posted before October 1st.”

Marie Ulven, a Norwegian indie pop artist who also goes by the stage name Girl in Red, is the singer behind the song that dominates TikTok today. Some of her other well-known songs include “I want to be your girlfriend” and “Girls.”
