The meme is that there was a manga where Giovanni was boxing with a Chansy. He lost in the end, but he was so badass doing it that Boxing Giovanni became a meme

Which is why they make perfect assholes as opponents, draining your pokemon's pp while constantly healing themselves(chanseys) just when they are about to die(chanseys)

Have you even played pokemon before? Chansey/Blissey=Most player's worst nightmare. They'll thunderwave you, then seismic toss you over and over (which always does damage exactly equal to the users level). Then heal themselves when they get to low HP. And it takes like 5 turns to get a blissey/chansey down to 1/3 health >>. Stupid high HP and Sp.Def
