The line comes from Billy Madison, the 1995 comedy starring Adam Sandler as the title character returning to school grade by grade. Today Junior became one of the film's most repeated catchphrases, a shorthand for impatience that fans kept quoting long after its release. On soundboards and in short-form videos, the stuttered version adds an extra layer of comedy, turning a stern hurry-up into a flustered joke. It endures because the situation is universal, everyone has waited for someone who is taking far too long to get to the point.
