Anyone who ditches or lets their friend down, usually to do some generally undesirable task, especially if it is taking blame, exhausting work, getting in a fight. A buddy fucker usually takes a lot of blame from his friends, and depending on how bad the ditching was, may not be friends with the fucked buddy much longer.
