alcohol is considered the social lubricant because it temporarily nukes the part of your brain for reasoning which is basically your mind. With out your mind holding you back by being attached to outcomes,consequences,anxiety and all that bs your free and you don't care what happens. The downside to it is hangover,sleeping with fat and ugly chicks, getting robbed, waking up next to 3 other dudes, and liver problems if you overdose. Its very possible to get laid with out it just don't let your mind hold you back. I personally don't recommend using external sources such as alcohol to get girls.
