Why it worked
The creator taps into a popular TikTok trend of questioning common items or concepts with "Tf is [X]?" This format is inherently engaging and shareable, as it sparks curiosity and relatable reactions from viewers who may also question the same things. By applying this trend to a variety of items, from tech to everyday objects, the creator maintains viewer interest throughout the slideshow.
Summary
The creator uses a series of slides, each featuring a common item or concept with the text "Tf is [item]?" to humorously question the perceived value or necessity of these things. The progression implies that the creator, a full-stack developer, is questioning trends and popular items, possibly to highlight the value of their own services.
