What's the biggest "inside joke" on your campus?

<ol>
<li>Everyone from out of state being from New Jersey or Long Island</li>
<li>Everyone in our upper-class cohort already attending the 4-year school or transferring from one local community college. First couple of weeks, the question was asked - “UMD or MC?” Of the 180 of us, I’ve only found 6 that transferred in from another school last year and only 2 from another 4-year school.</li>
