I think what happened is the Wesley twins noticed that they had contradictory beliefs:
“We’ve been to every room”
“We’ve seen the Chamber of Secrets on the map before”
“We haven’t been in the CoS”
Thus they know for a fact that something about the map is fucking with their memory or perception. Hence “Someone said a rude word.”
