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.
Wow the M4
s this year are arrogant, as always.
