Sometimes.
It depends on the person, how much alcohol they have consumed and what 'type' of drunk they are.
Aggresive drunk, attention seeking drunk, conversationalist drunk, crybaby drunk, honest drunk, lightweight vomiting drunk, rude drunk, sexual drunk, sleepy drunk, noisy drunk.
Alcohol consumption reduces a person's inhibitions and excessive alcohol consumption can temporarily remove them entirely.
This can lead to slightly aggressive people becoming very angry or verbally abusive and getting physically violent over the small things that they would have most likely ignored or gritted their teeth and silently felt annoyed when sober.
On the other hand it can lead to people being more sociable and very chatty.
Many people do behave very impulsively drunk when it comes to taking risks, only telling the truth or doing sexual stuff that they would not do sober.
