The word "bordel" means also a whorehouse (brothel, bordello) in French.
But it is also used as a synonym of "désordre" (mess, clutter, disturbance).
Of course it is not to be used in polite conversations!

Ta chambre est en bordel, va la ranger tout de suite!
(Your bedroom is a mess, go and clean it right now!)

If you want to amplify the notion of disorder or confusion, you can add the adjective "noir" (black):

C'était un bordel noir!
