The origin of sleeper build
Prior to being used to describe skinny-yet-swoll gymthusiats, the term sleeper build described PCs or muscle cars that looked clapped out but were actually straight fire. Sleeper build gained its new, and possibly more prevalent, meaning in August 2022, when TikToker @saifiev showed off his sleeper build in a set of viral videos.
In the videos, the skinny-looking @saifiev enters an elevator and then shows off his surprisingly large biceps. Other users dubbed @saifiev's body type a sleeper build, and the phrase took off (and inspired many, many derivative videos and photos) from there.
