mactíre
a mactíre is someone who slays so hard your life is just a sad side story that no one even reads.
You posted a sad poem. A mactíre replied with a rap about your life and it was fire.
You cried in your DMs. A mactíre sent you a message that said, 'You’re trash.'
You failed a test. A mactíre passed it and then roasts you in the comments.
