Get the mason jr.mug. (verb) The act of being hit (or hitting) by a car when people are not expecting it. Often pulled during exams weeks, by disgruntled or slightly drunk students. Mason Halling will bring large amounts of people to appear interested in your floor's situation for the next few hours before silence once again returns.
