A description used as a first name for a person who acts embarrassingly stupid or clueless. This word can also be used when someone does something embarrassing, and doesn't want to come to terms with what just took place (they blame it on their alter-ego, Barvis).
You accidentally walk straight into a conference room at your workplace where the CEO is meeting with high-level professionals. As everybody looks up in silence, you ask, "Oh, is there a meeting going on in here?"
After realizing the dumb-look on everyone's faces, you quickly reply, "I'm sorry. That was Barvis, not me." and quickly turn and walk out.
