The Defense chant became a staple of American basketball arenas in the 1980s and 1990s, led by arena organs and drum beats that prompted home fans to chant in unison against the visiting offense. In the NBA it is played almost every defensive possession, becoming instantly recognizable from broadcasts and video games. Clips of the chant spread online through sports highlights and meme edits, where it is now used far beyond basketball to mock or hype any stubborn defensive moment.
