Oatmeal Effect
When two people get the same stupid idea at the same time, like they were both thinking about the same dumb thing while also being high on life.
'We both thought of the same stupid joke at the same time, and it was like we were both high on life and also cursed by the same god.'
'We both came up with the same dumb plan at the same time, like we were both brainwashed by the same stupid idea.'
'We both had the same dumb thought at the same time, like we were both cursed by the same dumb god.'
