How well do you know your Fantasy Football slang?
INRS is an acronym people may use when messaging to emphasize that something is understandable and not too complicated. In other words, "It doesn't take a genius to figure it out."
The "it's not rocket science" saying dates back to at least the 1980s (although people may have used it before then). People then started using it in the late 1990s and early 2000s when mobile phone and Internet usage grew.
Nowadays, you will likely see INRS in messages or online, especially in tech forums. For example, your mom may marvel at your ability to edit video, and you reply, "I just gather the footage and try to tell a story based on the clips. INRS." Or you may offer tech help to your friend, "INRS. Just restart the computer by pressing and holding the button on the back of the computer."
