When you finish a work project in record time, and your team is giving you maximum love and props.
Different versions of the ‘Under Construction’ GIF, such as the one featured above were popular on the early Net. For home-based website creators especially, these GIFs were a way of showing they were hard at work building their sites, just like at a construction site. Many of the GIFs were based off of US road signage. Sadly, after the demise of Web 1.0 in the first few years of the 21st century, the under construction GIFs that frequented the likes of Geocities went the way of the floppy disk, surviving now in only legacy sites and GIF collections.
