The line comes from Sluipschutters, the Dutch sketch comedy show from broadcaster BNNVARA, where the Ron Jans character blurts out 'Ik dacht dat dat kon!' in a sketch revolving around smeerkaas, the Dutch cheese spread, appearing on a shopping list. The quote survived as a standalone reaction clip because it is short, quotable and endlessly reusable as a mock excuse. Passed around on soundboards and in meme edits, it is now mostly used by Dutch-speaking creators whenever someone needs a funny, deadpan defence for a questionable decision.
