A term used by wankstas to send a message to today’s youth to stay in school. The reason for the misspelling of "B" and c "kool" is another way of saying stay in school or your going to grow up to be a lossa with no job no education and a couple illegitimate children and a call from the Maury Povich show asking you to take a maturity test to see if you are the father of a 5 and a half year old boy which clearly isn't yours because you don't have the same bone structure but it turns out that "YOU ARE....THE FATHER!" and the next thing you know you get smacked in the head with a metal chair from your one night stand while she screams "YOU ARE MY BABIES DADDY!" and you wonder where the Steve the bodyguard is but then you realize that he’s on the Jerry Springer show.

stay in school, from peaches song "fuck the pain away"

In the Song "F*ck the pain away" by Peaches one of the lyrics is IUD SIS then later she mentions to stay in school
the acronym siply means "Stay in School, Injustice Under Dog"

An expression used by wiggers who worship that dickhead Vanilla Ice. However, the people who say this are being completely hypocritical because wiggers are known for not completing school. Also, many wiggers drop out of school in order to do drugs which they think makes them more cool as if they were to finish high school. Also, the "k" used for the word "kool" should be spelled with a "c" and the "K" is obviously a reference to the KKK, something that would not like a wigger. This expression was first used by Vanilla Ice in his 1992 movie "Cool as Ice" at the very end of the film, so that is obviously where the wiggers get it from.

1) Short for sister
2) In the song Fuck the Pain Away by Peaches, SIS seems to stand for Stay In School...

Can be known as the "Best years of their lives" for some..
but for most...total hella..and full of drama/stress and break-ups and stereotypes

Guy PrepsJocks, attend sports such as football, wreslting, baseball, they normally get the better looking girls while they have not much brains upstairs. Normally make nasty jokes about the size of their penis or how high they were the other day. Their normally tall beefy guys that all the girls drool over and are full of themselves and wouldnt be caught dead talking to someone of the lower class. Not all are like this though. listen to hip-hop and think their kinda gangster or they listen to poser alternative music.

Girl Preps These girls normally shop at abercrombie, american eagle or anchor blue. Their good looking and they sometimes put out. Some are sluts. Their mostly outgoing and are involved in leadership, student government etc. They like to party and are afraid of weed. NOrmally they walk around school with a purse, what retards. Oh and you cant forget the jeans with 10 holes in them. Listen to r&b singers and alternative rock.

Nerds They dont really give a fuck about where they fit in, they are to caught up in school and playing video games all day.

Gangsters/Me...

1.Great music people (mostly racist white people) think that is all about gats, sex, getting high, drugs, disrespecting women, drug dealing, killing people, jail, baby mama drama, getting drunk, dropping out of school, whips, going to strip clubs and Nextels.
2.But if you listen to some rap music, you'd seee that now a days it has inspiring messages such as stay in school and don't do drugs.
3. Music highly preferred by black people and prefferred to be sung by black people, but white people TRY to rap anyway.
