You're clearly being dumb by doing this, you're not cool by doing this, and one single report from anybody (which will 100% happen) will make you get instantly flagged by Riot and banned for 7 days (or even more depending on previous bans). I'm just saying this so people stop saying stupid shit at the end of the game and have to instantly regret it because of Riot's very strict chat restrictions. Literally even saying some of the light swear words will get you flagged by Riot if you had a history and someone reported you and get you banned for a long time.
