Family and or New Member class names

[texas_09]

At my chapter we have family names, I'm in the tiger family (almost every single gift we get from our bigs has tiger print on it) there's also the zebra fam, the argyle fam, and a couple others that i forget (i'll have to pay extra attention). I've also heard from friends that are a xi d's at other schools that some groups do combined last names and change them as people come and go.
