Ghetto acting interests

A friend and I were talking last night about a certain college in our area that we feel is truely the epitome of "ghetto". There are Greeks on that campus as well and we were discussing about what their informationals might be like considering the school. Greeks have you ever had people show up to your informationals who you knew there was just no way they would ever wear your letters by the way they carried themselves? What are some absolute no no's that you have seen or know you would not allow to pledge your beloved orgs. ?
