The phrase comes from Donald Trump's 2015 presidential campaign announcement and subsequent rallies, where he promised to build a wall on the southern border of the United States. The repeated wording made the line highly quotable, and short clips spread across YouTube, Vine, and later TikTok and meme soundboards during the 2016 election cycle. It became detached from policy debate and reused as a generic reaction to any large building project or barrier. Its continued use reflects how campaign soundbites can become permanent internet shorthand.
