1. Annoying, cocky
, aggressive, sarcastic, crazy or otherwise abnormal/different attitude or personality displayed by someone only when they are drunk or under the influence of alcohol
If a person who could normally be described as kind, funny/witty and smart becomes a sarcastic, insulting, rude, foul - mouthed bitch, while drinking alcohol.....the bitch has a drunkitude !
A usually quiet, laid back, and/or somewhat shy person becomes a loud, over-talkative windbag almost immediately upon consuming alcohol....has a drunkitude or a drunkonality
as opposed to their personality.
