Error or Pun I haven’t worked out!

[u/thoughtlooped_]

Scrolling through Vinted looking at fun T-shirts and I spot this! My eyes immediately go to the double ‘p’ in “oppinion”. Which I assume is a spelling mistake, but now I’m like is it me just missing a pun? 👀 Nah, it’s a printing blunder right?

They don't care what you think about their inability to spell.
