The name points to Shiggy, the comedian and influencer whose 2018 "In My Feelings" dance challenge, tagged #DoTheShiggy, became one of the defining viral moments of that summer. This particular clip is a different artifact: a two-second vocal "ayo" whose published source is an Instagram reel, tagged with shiggy, ayo and nyc. Short shout-style callouts like this travel well because they need no context, and the New York flavor in the tags helped it settle into meme edits, reaction compilations and street-style vlogs, where a burst of attitude works better than a longer quote.
