Sticker is the title track from NCT 127's third Korean studio album, released in 2021, and its chorus plays on the line like a sticker as a hook about attraction sticking like a sticker. The phrase became a memorable part of the song for fans, and short, boosted clips of the chorus began circulating on TikTok, YouTube edits and soundboards. The earrape version leans into that memorability, turning a polished K-pop chorus into a loud meme sound that still works because NCT fans instantly recognise the reference and the joke lands in seconds.
