When people are drunk enough to be annoying, you can ignore them, leave the premises and go home, and within 30 seconds they will have forgotten all about you and never notice that you abruptly disappeared. I do this all the time. I'll push to a bar with all my colleagues, then play a round or two of pool as I wait for everyone else to get good and liquored up. Then I discreetly make my exit, and all anyone remembers the next day is that "yeah, Avenger was there last night." Thus I get social points, without having to suffer through too much.
