NPC sororities with calls?

[ajuhdg]

I could be wrong, but if what I remember from my school is correct the historically black GLO's use their calls very much in the open. I remember the first time we I was at a Greek week event and they called for the DST's and the noise they made scared the crap out of me! But it was an amazing attention getter, I looked forward to it every time after that!! The same is true for the AKA and also the male orgs! The NPC and IFC all had cheers and such, but no 'calls'!
