Short spoken clips like this one spread mainly through soundboards and short-form video, where a brief, memorable phrase can become a reusable reaction on its own. Listeners save the best shirt off line for edits that need a quick, lighthearted payoff, and its appeal comes from how easily it fits different visuals rather than from a long scene or detailed backstory. Because the clip is only about three seconds long, it is easy to trim and place at the end of a joke for a quick payoff.
