Being authentic is often considered a valuable trait, but sometimes we find ourselves in situations where we need to pretend or fake something for social or professional reasons. In such cases, there are many synonyms for "fake it" that can come in handy. Some alternatives include "exaggerate," "inflate," "fabricate," "feign," "simulate," "mimic," "pose," "pretend," "simulate," "act," and "play-act." Each of these words has slightly different nuances and connotations, depending on the situation and the level of deceit involved. Whatever word you choose, remember that faking it should only be used sparingly and with good intentions.
