True facts: your environment and social setting makes a huge difference to getting drinking right.

Being out in a club/pub/bar with friends and other people especially when loud music is playing will generally provide a massive upbeat to your drinking experience. Hence when people get drunk in social settings such as clubs they tend to relax become more confident and lose their inhibitions and generally dance (that has everything to do with sex, lust and dancing mimicking sexual contact)

Being drunk in a quiet place such as a home will generally leave people sleepy/depressed since the alcohol will have a negative effect on the person, reality is that your inhibitions and everything are just as lowered but the lack of the club environment means that the open state of mind and "good time" is not had.
