I don't give a shit is a popular phrase to be used when you are not interested in what someone else says or believes. It implies that you don't even care enough to physically give them a sample of your fecal matter.
Gamer 1#: Dude your computer sucks, you shell out $2000 for a kicass rig, and still run it on a piece of shit CRT monitor.

Just like any other club, except that that there is a stage often featuring fixed metal poles. The main attraction are strippers - women who dance in erotic way using the abovementioned poles, with most of their clothes off for you visual pleasure while you sit back and drink beers with your mates. Often they will let you get close to them, most likely for you to give them a tip if you are enjoying the display.
