The phrase combines rizz, the Gen Z slang for romantic charm popularised on TikTok in the early 2020s, with white tees as shorthand for effortless style. Clips using the sound spread through short form edits where a plain outfit is treated like a power move, and the joke is repeated with mirror selfies, outfit checks and confident walks. Because the wording is vague enough to fit many creators but specific enough to be recognisable, it stayed useful as a reusable reaction and transition sound rather than a one off joke tied to a single post.
