The Latest TikTok Trends in September 2021

Read below for the details or watch the full compilation here!

One of the Biggest TikTok Trends in September 2021

1. Good Soup

@itsjacksonjansenIb: @futuremilfclub♬ good soup – MARVEL FANS

This iconic sound is from the TV show “Girls” where Adam Driver takes a sentimental spoonful of soup and says “Good soup”. Now, this is one those things which TikTok creators decide to blow up for no real reason. But I can’t tell you just how many genuinely hilarious TikToks there are to this TikTok Trend in September 2021.

2. Berries and Cream

@salamadunkThey will grow out… EVENTUALLY 😩 #badhaircut #bangs #MyTeacherWins #berriesandcream #fyp♬ original sound – Justin McElroy

This sound from an early 2000’s candy commercial got hugely popular recently. After some creators realized their new haircut made them look very much like a certain character in the commercial or when they wanted to showcase some goofiness, they used the sound to poke fun at themselves.

3. Starbucks Cake Pop

@sarinasayahhcake pop♬ original sound – Cake Pop Guy

Made originally by the now aptly named creator @cakepopguy this trend is all about the twist. The cake pop guy going “Is that a Starbucks cake pop?” with his unexpected falsetto has captured the laughter of many. This led to numerous collabs with big creators, boosting the trend greatly.

4. Double F.

@majiqmike Yeee there’s no more hope for me😂🤓 #short #foryou #foryoupage #trend ♬ Originalton – Beste_Doku_Szenen

Explained very simply, this TikTok Trend in September 2021 is for those times when one F just doesn’t cut it.

5. When a Girl Has Only One Thing On Her Mind

@ellaisannoying74obsessed♬ original sound – brinilly

One of the open-ended TikTok trends in September 2021, this one paves the way to some pretty funny commentary on what girls really have on their minds.

6. I Said Hey, He He He

@brodaloriansurprise!♬ original sound – tdenning

This TikTok trend is one of the most creative ones we’ve seen in a while. Using the popular song TikTokers have created a whole new format to make fun of their daily lives.

7. Getting Arrested

@jacobemilePOV: you’re caught trying to escape from the farm #fyp #moo♬ son original – FYP🖤

Yes, you’ve read it right. Getting arrested is a TikTok trend now. Creators have been pretending to be arrested while flirting with the camera. It’s one of those things that make you certain you’ve had enough internet for the day.

8. Mama Said That It Was OK

@rodReply to @susanr297 I look up to him a lot #work #theoffice #employee♬ Mama Said – Lukas Graham

Who is your role model for some of your weirdest habits? This trend lets you make some pretty dubious preferences.

9. Dance Moves

@collinhuskeyYes I should be studying #UltaBeautyatTarget #TalkCurlyToMe #medstudent #doctor #premed #studytok #medschool #trend #fypシ #medicalstudent #dancer♬ Believe Me – Navos

A recent TikTok trend in September 2021 is helping people out with their dance moves. Got some unique moves you’d like to showcase? Then this one’s for you.

10. Girlbossed A Little Too Much

@toxicthotsyndromewait is this not summer camp 😆♬ original sound – Carol.ine3

Is it possible to be too successful? Well of course it isn’t! But this trend helps those who’ve been hit with some unexpected situations to have a little fun with it.

Bonus: I’ll Cry If I Want To

@phaithmontoyalike it’s hot asl outside what else were we supposed to wear 🥴♬ original sound – ineffablehaven1

This TikTok trend is for all those assumptions that you’ve later on realized were untrue and even toxic. It provides a pretty helpful commentary on important social problems as well.
