Morphology
The expression is a literal negative imperative composed of 'don't be' + the noun 'bastard'; if a learner knows 'bastard' as an insulting word meaning an unpleasant or cruel person, they can directly infer the meaning 'do not behave like that person'. The construction follows a standard compositional pattern (don't be + noun) so it is semantically transparent, although colloquial and socially taboo in register.
Etymology
Don't be a bastard uses the old word bastard, which once meant a child born to parents who were not married. Over time bastard became a strong insult for someone who is cruel or unfair, so the whole phrase tells someone 'don't be mean'.
