Its a Dota2 meme that started when a pro player Quinn malded over someone picking Pango as their hero.
Dude can you pick a real hero HOLY crap why are we picking pango in 2023? Arent you tryign to play pro or soetmhing? How about we play heroes that arent the objective best heroes in the game? You're genuinely a horrible horrible player. You just draw aggro off cooldown. I lost all respect for you. Imagine trying to play pro and picking pango every game in pubs. Truly disgusting. Your'e just a coward tbh. You dont know whats good against lesh so you pick pango cause its easy. Every game you pick that hero you get worse. And you're already horrible.
