Might have to start that ;) I think it's Be the Best, Pledge the Best...something to work towards.

Yeah, but there can be a spectrum of things between true ritual and cute sayings. And I remember discussions on GC about whether letter closings like SLAM and YITB are considered secret or not—some were surprised to learn they're not. I can easily imagine things that aren't ritual per se but are rooted in ritual.

But yeah, people should know better than to ask in a public forum.

Alpha Xi Delta has a couple of those. One is not ritual, but I would say still secret. And not used so often that every sister everywhere (or 40 years later) might remember it. But I wouldn't ask on an open forum.

The other part I found odd is, not that I know a ton about Tri Delta, but I've never heard of a sister called a Delta. That alone raised a red flag. I couldn't have answered her anyway, but I would have cautioned any of my Tri Delta friends to answer with caution, if it's a secret that people care about keeping. Maybe it's not a big deal though.

Totally random and probably off topic, but at Mizzou the Tri Deltas sometimes go by "Deltas." My D has a friend in that chapter.

Bound By Poseidon's Belt?

Better Buy Peanut Butter?

A lot of the women in my collegiate chapter call each other 'Deltas', so it may be a newer thing. I know that when I was a collegian 2-3 years ago, it was pretty common.

However, to answer your question, you need to ask one of your sisters or an officer. This is not the place to ask questions about things like that.
