Learn to Detect Humor
Sometimes I really wonder how it is possible for some league players to be on the internet and be utterly unable to understand even the most basic humor. Because somehow people don't understand that calling my adc my true love is not a diss on their person. I don't even understand how that was a bad thing I did but whatever I guess. Now I'm not saying you have to all of a sudden be able to understand all the dirty jokes in Shakespeare plays but at least learn to realize a <3 bby is not an insult to your person. It's even better for you in the long run, this way you won't get triggered everytime someone makes a joke that isn't all ponies and sunshine.
PS: Also "I would have landed that skillshot if you didn't get a speed boost" and "you are bad even though we lost lane 0/6 against you" are something you shouldn't say after winning a 4v5. It just makes you look sad.
