New kids at the school, first years, naive young student that U4s and above may laugh at and bully for their entire first year before they are accepted into the college.
Bottom of the school heirachy, annoying M4s should be bullied in boys case and bitched about in girls houses, until they are properly behaved.
Sucking up to/ making friends with M4s is forbidden in their first weeks at school.

An extremely powerful assault rifle used by special forces and the U.S. military; it uses the 5.56 mm round. An M203 (grenade launcher) can be attached under its short barrel to cause maximum damage and doom. It is black with pink polka-dots and a lot of naked lumberjacks use them. Lumberjack slams are also delicious. They are eggs, ham, bacon, sausage, pancakes, and parsley. They taste slammingly tasty.
That stupid asshole was running down the hill when he tripped on a rock and the M4 Assualt Rifle he was carrying went off and shot a mailman.
