What song is it?
The trend uses a short grime freestyle that opens with a mic check — “check one, check two” — and goes straight into fast, aggressive bars. The verse is widely credited to JME. Genius lists it under JME in “Boy Better Know Freestyle (GRM Gold)”, described as a BBK freestyle from around 2010, with Skepta, Frisco, Jammer and Hammer MC on the same session. The full lyrics are on Genius; we don't reproduce them here.
On TikTok the sound is labelled “original sound”, not a released track. Subtitled clips of the freestyle were already doing millions of views in 2025; the AI version took off in October 2026, when a free CapCut template called “JME Rap check 1 check 2” let anyone put a face on it. How that works: the check one check two filter guide.
Who is JME?
JME is a grime MC from Tottenham, North London, and a co-founder of the collective Boy Better Know with his brother Skepta. He is known for quick, deadpan, tongue-twisting bars — which is exactly why the verse works as a meme: it sounds ferocious coming out of anyone.
What “check one, check two” means
It's the oldest line in live sound: what an MC or engineer says into a microphone to test the levels. In grime and pirate-radio sets, opening with a mic check is also a statement — the MC has the mic now. In the trend, that energy lands on a toddler, a mum or a presenter, which is the whole joke.
Dyslexia Freestyle, check 1 check 2 and the Luke Dean track
- “Dyslexia Freestyle” — a fan nickname used on remix uploads, not an official title.
- “Check 1 check 2” — the same thing as “check one check two”; people caption it both ways.
- Luke Dean, Locky & JME — “Check One, Check Two” — a separate house track built around the line (Apple Music). Not the sound the trend uses.
Which TikTok sound to use
Check One Check Two AI videos are silent on purpose — we don't ship the recording — and 9 seconds long, the same as the trend sound. In TikTok tap "Add sound" and pick the 9-second check one check two sound ("original sound – FIFI MFC VRFS") — it starts on the first bar, so it lines up from 0:00. Got the longer 28-second freestyle sound instead? Drag its start to 0:03.
