This counts if he uses the term, either while talking about the debates or during the debate ("I'd like to thank Sleepy Joe for staying up past his bedtime to join me in the Battle Box"), but not in cases where Trump just alludes to the verbal slip-up. This will also resolve to "yes" if he describes it that way in retrospect, though I don't think this particular line will stay in circulation all that long.
