Damian Lillard is a proper noun, referring to the American basketball player. In general usage, treat it as two names joined by a space rather than a verb. It denotes a personal name with two elements: 'Damian' (first name) and 'Lillard' (surname), often invoking his identity or actions associated with him. In some contexts, you may encounter the phrase as a playful verb, though this is nonstandard.
