“I Know Ball” is a TikTok trend where you show off a specific skillset. The term originates from basketball, when “knowing ball” meant that you understood the game. With the “I Know Ball” trend, the poster refers to something they’re good at by saying “When XYZ acts like I don’t know ball” before posting proof of their skills via images captioned “I,” “Know,” and “Ball” (or another variation of the phrase).
- TikTok Example: On August 29, 2025, @bellaamiina posted a TikTok with the caption “When I walk into Sephora bare face and they think I don’t know ball,” before showing off a full beat of makeup with the caption “Baby I know ball 💋”
- TikTok Example: On September 4, 2025, @kg__golf posted a TikTok with the caption “A group of girls walked past me and I ignored them. They said I don’t know ball,” before showing a picture of him and his girlfriend with the caption “Trust me. I know ball.”

Open a few pics or vids of you doing the thing you want to show off. It can be anything you're good at like, a sport or a hobby. Grab some photos or video clips of you doing the thing you want to show off (as well as a few regular shots of yourself) and open them in the TikTok editor.
- Pick at least 3 photos so your audience stays engaged and has something to swipe through.
- Keep it to 5-7 photos total. Fast food & social media expert Wayne Dang says to “try to make the video as short as possible without sacrificing quality and detail. Any unnecessary information will likely make the viewer click away.”^{[1]

Start with a photo of yourself as the first in the slideshow. Then, organize the photos or videos of you with the thing you want to show off afterwards. If you choose a video, make sure it’s at the end so users get to through the rest of the content quickly.
Use the text feature in the TikTok editor to add a caption to your first photo. Caption the first photo “When I [do something] and they act like I don’t know ball” and make sure to replace the placeholder text with what you want to show off. Then, caption your subsequent clips with “I know ball” or “trust me, I know ball,” breaking the words up between images. Once you’re done, click post!
