Guild Wars 2

Jetsam Isle in Lornar’s Pass. “Ousted Captain Jetsam” says “think” instead of “thing”.

Might be his weird pirate accent though?

That’s a common saying where I live. It’s kind of a joke way of saying it.

It’s a fairly common phrase in the UK, saying someone has another think coming is another way of saying they’ll need to think again.

That’s not necessarily a typo. The actual phrase is, indeed, “another think coming” and not “another thing coming”. It was misheard and misspoke so often that “thing” became the accepted version in many places.
