When you spell something based on how it sounds rather than how it's actually spelt, similar to the famous Ken Lee video.

Movie theaters have a very simple etiquette. Don't talk, silence your phone & keep it put away. Be mindful & respectful to others. At first it was harmless, people would briefly clap to a Stan Lee cameo and continue with the movie. As marvel movies got more popular so did clapping for Stan Lee cameos which went on longer than it should and this is where the Stan Lee effect began. It became obnoxiously normal for people to lose their shit when Stan Lee was on screen to where movie etiquette was completely forgotten. And now the Stan Lee effect has spread to different movies for example Shazam! After a really cool reveal one guy started clapping really loudly then the whole theater started clapping and continued to clap over a few seconds of dialogue. That's TOO MUCH CLAPPING! JUST CLAP AT THE END!
"Why the fuck is everybody clapping? I can't hear what's happening in the movie!"
"It's the Stan Lee Effect, some of these people might be genuine fans but most of these people are just clapping because someone else is, or they wanted to feel special and start a clap wave."
"This isn't even a marvel movie!"
