The phrase just put it in the net is a common sideline and commentary expression in goal-scoring sports, especially football and ice hockey, where fans shout it when an attack builds up without a finish. As a short standalone clip it spread through sports meme edits and soundboards because the line needs no context to understand. Its appeal is the mix of obvious advice and total exasperation, which makes it reusable for any sport, game or everyday situation where someone overthinks the simplest possible ending.
