Top definition
A person who constantly makes social interactions awkward, generally due to defects in their personality or after imbibing large amounts of alcohol or sometimes both. This person does not have a social radar and often kills conversations dead in their tracks. Speaking to this person often is about as pleasant as rubbing sandpaper on your face.
