De kater komt later is a well known Dutch expression, with kater meaning both a male cat and a hangover, used to warn that the consequences of drinking arrive the next day. As a short audio clip it circulates in Dutch meme edits and reaction videos, where the spoken line is reused out of context for any short sighted choice. Its appeal online comes from the timing, a calm warning placed after reckless behaviour, and from how easily Dutch speakers recognise the saying while others quickly learn it through the edit.
