maddiff
A maddiff is when someone loses their mind over something tiny while everyone else thinks it's nonsense. The person who is mad never says they're mad, only the people watching them know it.
My cousin got a maddiff because someone said his pizza was 'okay' instead of 'legendary'.
My mom had a maddiff because her coffee was 1 degree too hot.
My friend had a maddiff in the comments because someone called his dog 'chonky' instead of 'gorgeous'.
