SP aka sh*t pill has evolved through many
generations of students at a
particular private boys school.
Generally it refers to someone who has an outwardly bad haircut, thus pill referring to head or hair. the term is used in a derogatory sense; whereby it works to belittle the person who has to bear the
unfortunate reality of having a bad haircut
Usually, the term is said at the beginning of the day when the student first enters school and or is used the first day(s) back from term holidays etc where they have been made to get their 'pill' chopped.
Bad haircuts, sh*t pills, or simply SP's can include such styles as short at the back and long at the front, attemped mullets, and 'muzztek' cuts on people who are in fact, not ethnic. Also, crew cuts on people who usually do not have such cuts are branded Sp's
People who encompass Sp's are put down for days, even weeks on end up until their haircut is restored to a NP, or normal pill. Girls usually stay right away from boys with sp's and rightly so.
usually go by the name 'pat' and or other variations
