Noun: A somewhat vague term, but usually something a person has done unexpectedly when in a moment of inspiration or some form of epiphany. It can also be something a person does to trick or deceive someone. It can either be positive, negative, or just unexpected and/or ironic.
A flipjob is when you realize you have forgotten to pay child support and promptly leave work to drop off the check and end up getting fired. It is pulling a 180 on a busy street because you realize you're truly in love with a woman. A flipjob can also simply be when your mind jumps to a random thought and is captivated by that instead of anything important. Also, may be a reference to "flipping someone the bird" when they didn't think you had the balls to do so, or possibly even rolling a cigarette of some type.
