Wait, I'll answer that for you... F%@! No!!!

Reasons?

1. Drinking + a Self Contained Underwater Breathing Apparatus = fatality for you while trying to hit on a hot girl. Infact many fatalities. Bro 1 - "Hey man, how was the underwater club tonight?" Bro 2 - "Not bad, only 15 people died tonight...BUT thank God none were hot chicks, just a few douche-bags who were crushin' back jager-bombs" Bro 1 - "Cool man" 

2. Excessive Flatulence. Say you stopped by TacoTime for a couple Super-Beefs and hot-sauce before hitting the Underwater Club. Man, there ain't no way you could hide those bath-bubbles while mingling, plus not to mention the dead floating fish dwelling in your area. You'd be bombing and flying solo alone that night faster than Justin Bieber competing at a talent show.

3. Shrivel. So you've been underwater and hand-signing with a hot lady for an hour, drunk and half dead. By the time you get out of Underwater Club you're outtie has turned into an innie to say the least and your hot lady looks like she's 90yrs old, we're talkin' water logged beyond recognition. Nothing worse than 90yr olds pounding.

Enough said, or what do you think?
