The 'That Wasn't Very Cash Money of You' meme features a cool, sunglasses-wearing version of the character Godzilla paired with a catchphrase expressing ironic disapproval. The term 'cash money' functions as slang for 'cool' or 'righteous,' making the phrase a humorous way to tell someone their actions are unacceptable or disappointing. While the image of Godzilla in shades dates back to promotional material and earlier internet culture, it became a viral sensation around 2018 on platforms like Tumblr and Reddit. It is now the go-to reaction image for highlighting selfish acts, broken promises, or any behavior that lacks 'cash money' energy.
