7/2 is *not* the computer hand. Q/7 is. The reason Q/7 got that name was because, according to a computer simulation run back in the early 1980's (I think) that was the lowest hand that will get you a profit if you get called by a random hand.
7/2 is sometimes called "The beer hand" because it's so terrible that people will often fold it out of position so that they can go get a beer. But some people call any cruddy hand a beer hand.
