Explanation

And a dull day in traffic court will be sparsely attended, but during a dramatic celebrity trial the courthouse is bound to be jam-packed. This adjective is informal, dating from about the turn of the twentieth century. Earlier it was jam-full — both come from the "squeeze into a space" sense of jam.
