Just something I wrote up for kicks here are 5 ways:

1. Step on their shoes. I'm not even talking about hurting their feet, but a lot of people in all walks of life would go apeshit if any speck of dirt or damage happens to their shoes. Which is bullshit, because shoes are designed to protect your feet from harm and dirt. Yet, so many people wear these $200 shiny and new shoes and expect them to stay clean and untouched with each walk. And contrary to popular belief, it is men that complain about it more than women.
2. Like something others hate. A common problem is that whenever someone dislikes something, whether it's a show, movie or game, that they feel the need to make others not enjoy it so they don't feel alone on this. I like to call it Marge Simpson syndrome.
3. Ketchup. No word of a lie, in certain parts of the world especially in the States, people will either roll their eyes at you, insult you or downright even try to fight you physically if you request ketchup. Especially in Chicago on Hot Dogs. Let me ask you assholes who agree with that bullshit. Are you the one paying for the food? No. Are you the one eating the food? No. Then shut the fuck up.
4. Exist. No word of a lie, there are some crazy people out there, for various reasons both common prejudicial and even more non-sensical reasons that get easily triggered by you existing for one reason or another. The Karens being a huge example of that.
5. Mention the word "Concussion" to a hardcore NFL fan or a Rep from the actual league. Now in the League's defense they're trying to balance out how much money and fans they may lose should they try to make football safer for the players. However, the way they approached the concussion scandals, by denying it constantly rather than owning up to it and maybe compensating the players that worked their bodies out trying to make them money, is grossly disgusting. With the Superbowl coming up and the fact that they never dealt with it properly still, makes this a timeless issue.

Thank you for listening to my funny nonsense.
