You will want to go dancing, since that's the only thing to do there. The music is so loud you can't have any conversations, the drinks are expensive as fuck, it's like you try to order a beer and they'll want one of your kidneys in exchange. The girls are not interested in being picked up at all (and who could blame them when there is always a threat of knockout drops and similar horror stories), they only want to dance by themselves. There are tons of drooling men trying to desperately hit on the girls with zero success, yet the men won't understand getting rejected, claim she must be on her period and just go to the next girl. You will see lots of hot chicks with noses high up in the air, and you will witness awkward flirting attempts, maybe a fist fight or two because hey man, how could I know that she had a boyfriend, man? I was just dancing yo and she was shaking that ass and I was like yo, you're mine now, man, I didn't anything bad, okay? Just chill now, alright?!
If you don't like dancing, well then, Just enjoy the music, that's it.
Then, later. As the hours go by the crowd gets sparse. Late at night, four or five a.m., most clubbers will have left. Only the most desparate and/or drunk will stay, the left-overs! Looking at each other through their blurry and tired eyes, stomachs full of fancy drinks and gallons of beer and booze, almost falling off their chairs, and the marbles in their head will bump at each other in unexpected ways. They will realize that this is the final chance, this is it now. All or nothing! And then they will rise, clumsily standing up, stumble towards each other, grunting something totally incomprehensible, laughing about absolutely nothing then falling into each others open arms and sticking the tongue into their mouths. This unromantic and unappetizing experience is actually the true reason why somebody would want to go clubbing. Scored!
Otherwise, just enjoy yourself there, have fun and don't mind if your dancing skills are awkward, that's okay. All eyes on you! Give it all you've got!
Well fuck I thought I was listening to David Attenborough in my head when I read your post lol.
Well reading your post seems like not much has changed since I last went 15 years ago.
This is what I told you a few months back (well especially the bold).
