The verb 'betiteln' (to title / to call) is made up of the noun 'der Titel' (title) and the prefix 'be-'. It means 'to give a title' and is an inseparable verb.
Wie wollen wir das neue Projekt betiteln?
What do we want to title the new project?
The sentence structure reveals the meaning: the derogatory label for a person requires the preposition 'als' (as) (jemanden als Lügner betiteln = to call someone a liar). When a work is given a name, the title often follows directly or appears in quotation marks.
Sie betitelte ihn als Feigling.
She called him a coward.
In the meaning 'to call someone something (derogatory),' the preposition 'als' is required. The structure is always: 'jemanden als etwas betiteln' (to call someone something).
Nur weil er einen Fehler gemacht hat, sollte man ihn nicht gleich als Versager betiteln.
Just because he made a mistake, you shouldn't immediately call him a failure.
