Actually, this reminds me a lot of the commercial for the Marines--"The Few. The Proud. The Marines." I thought more of a patriotic/pride type thing--pride in one's self as a member of Beta Sigma Phi and pride in the organization as a whole. I do agree it's a hard them.
I do know that there has been discussion elsewhere and Karen referred to this.

In our motto, "Life, Learning, Friendship," LIFE has pride of place,
because without it there would be nothing else. Life leads us to all that is Good, True and Beautiful.
Hope that helps!
