A Bash for me is a little like an intervarsity, ktm team, bmw team, yamaha, .... You drink to much, but there is always someone beating you, talk a lot,,,,, eat meat (on last one in rhodes). Let your hair down

I have not seen people riding bikes drunk and do stupid things, i have attended 3 national events, i leave my wife at home, not her cup of tea, but can recommend it, it is different for everyone, and you do not need to stay up all night, find a quiet spot, not that easy, and go and sleep. Normally not a problem if you had a long ride.
It is stress release, you have to consentrate when you ride, rlax with fellow bikers, you arrive home, feeling tired but ready again to tackle day to day stuff.
