Loudmouthed
Loudmouthed is an informal adjective used to describe a person who talks excessively and often in an abrasive or boastful manner. It implies a lack of consideration for others' listening capacities or the social appropriateness of their speech. The term suggests a volume and persistence in vocalization that can be perceived as irritating or overbearing. Someone described as loudmouthed may dominate conversations, interrupt frequently, or express opinions with undue forcefulness. It is generally a negative descriptor, suggesting poor social skills or an inflated sense of self-importance. The connotation is not necessarily about the physical loudness of the voice, though that can be a component, but more about the nature and quantity of what is being said. The behavior can be seen as a deliberate attempt to command attention or assert dominance, often without genuine substance to back up the volubility. It's a characterization that implies a deficiency in tact and discretion.
