General insights

I think that a lot of people forget (and underestimate) the ageless tactic of booing someone. Nobody likes to be boo'd and in doing so, you are immediately (and publicly) cancelling them. It's important to note that timing is key. A loud, well timed "boo" will provide the maximum amount of "burn" and its aways best to boo a person mid-sentence. Also, try to ensure that the boo occurs at the beginning of your encounter. This is when all of the person's energy will be focused on creating a chain of coherent thoughts. The beauty of the boo is that it's unexpected. This is because the person believes that their opinion is both irrefutable and socially acceptable. The boo will disrupt the ebb and flow of their thought processes and they will experience a crippling brain-glitch. If they keep talking, you can employ a very drawn out booooooooooooooooooooo until they become flustered and stop. This is when you have a good opportunity to walk away. Days later, the person will decide that they have constructed the perfect rebuttal and you will be nowhere to be found, thus creating additional frustrations. If you don't already use this tactic, feel free to add it to your arsenal of mental weaponry.
