cryptic behavior

Puzzling, secretive actions

Cryptic behavior is conduct that is mysterious, secretive, or difficult to interpret.

Someone exhibiting cryptic behavior may give evasive answers, act strangely without explanation, or seem to be hiding something: His cryptic behavior before the party made sense once we realized he was planning a surprise.

The phrase often implies suspicion that the person knows more than they're revealing.
