maddiff
A maddiff is when someone gets so annoyed about something so small that they almost throw their phone. No one else gets it, but they do.
My mom had a maddiff because someone spelled 'maddiff' wrong in a tweet.
My brother had a maddiff because his phone was 0.5% slower than mine.
My friend had a maddiff because her coffee was 'okay' instead of 'amazing'.
