The line is closely associated with Matthew McConaughey’s performance as David Wooderson in the 1993 film Dazed and Confused. Over time, that relaxed “alright” delivery became a widely shared reaction clip in meme culture, especially in short edits and compilations.

Its staying power comes from how recognizable McConaughey’s drawl is, even when the clip is trimmed down to a very short soundbite.
