Hearing "Yaas"es from snu house

Recently I was walking past a house where several snu members are known to live. I heard several members loudly shout "yaas."

Previously I had perceived Snu to be a prestigious all-around top house. I've never been so turned off in my life.. yaaaAAAAAAAAAAAAAAAAASSSS i swear one of these lasted for like 10+ seconds.

would've expected this from mids (pike/ato). I thought snu didn't have a capella members.
