on planet supersizeme, you earn the title of "tool" by thinking you are much cooler than you actually are in real life. it can be someone who is always talking and won't shut up, thinking they are hilarious and that everyone is interested in what they have to say, which is for the most part the most asanine shit to come out of a human being's mouf. if you are arrogant and conceited, you might just be a damn tool.
you also can become a tool by being an all around idiot and becoming a liability to be out with in public. i was out with someone who was acting quite toolish this weekend. he was a liability to the enth degree. this guy was recently divorced, drunk as hell, and on a mission to get laid. and for every girl he went up to seeking to secure the holy vagina from her, it made me cringe and want to move to the other side of the bar.
tools!!!
