McMooch

A nick name for any of your Irish friends that have a "Mc" in the front on their name that are always mooching. Bumming cigarettes, beers, food, clothes and just about anything they can mooch. They will most often "forget" their wallet when eating out and have to borrow though never to pay back. They can however be very generous when money is available to them and blow through it immediately which is why they never have anything.

The friend that never orders anything at Mickey D's for various reasons, (low on cash, diet) but will never hesitate to snatch some fries or ask for a sip of coke
Also means to mooch off someone's McMeal and to overstay one's welcome on the tray

The act of approaching and restricting an unsuspecting friend and slowly driving your fist into the side of their rib cage, constantly increasing pressure and violently twisting your fist back and forth like a rig drill. Its very painful and uncomfortable.

While applying the torture treatment, it is common to shout out "Mega McMooch mule rig drill rib driver!"

It is also common practice to engage in the act of making a fist and twisting it just enough to let your victim see it happen a few times, minutes before its coming. This helps immensely to build anxiety in the target.

It is much like a noogey but applied to the side rib cage.
