Here are some of mine:
1) When people call 'lives', 'mans'. As in "HE BRO U GOT AN EXTRA MAN!" or "OH NO I LOST A MAN!" It's a 'life' or multiple 'lives'.
2) When people call the rings in Sonic The Hedgehog 'coins'. There's a fucking difference between Mario and Sonic, and a differences between a coin and a ring, that later of which has a hole in it. DO YOU CLAIM THAT THE PLANET SATURN HAS 'COINS' INSTEAD OF RINGS?! :plsgo:
3) When people pronounce Mario (Mar-ee-oh) as fucking (Mare-ee-oh). I don't care that you're a third generation removed Italian from Strong fucking Island, Nintendo and Miyamoto himself have pronounced it (Mar-ee-oh).
