I've heard it mentioned before in various writings I've encountered, including novels, and the president of the chapter on campus here was talking about it last night.
And I was wondering, is this something unique to Sigma Chi or do other fraternities do this too?
I will say this much--after last night's tour of the first four houses and meetings of rush, I'd have to say Sigma Chi is the clear frontrunner.
The other four houses are tonight, though.
