If, in a nightclub's seating area you happen to end up next to someone hot while they are trying to get with someone else you may make yourself appear to be very drunk in order to distract the guy/girl from your rival. These actions can be anything from falling on top of the couple in order to prevent them from hooking up or you could stand up and act as outrageous as possible to focus the attention on you. Works even better with an accomplice--twice the tactical drunkenness is twice as good!
You: Dude what are you doing you've only had two drinks!
Friend: Shhhh! It's alright I'm being tactically drunk...I need to distract these two! Care to help?
You: Sure thing! (You then proceed to dance in a manner that really just can't be ignored while your friend does his own thing.)
