Tri Delta VS Tri-Delt

[jennyj87]

At my chapter we were always told that the proper "nickname" was Tri Delta, no Tri-Delta, no Tri-Delt. I would always aruge with my friend who goes to FSU cause he would call me a Delt or a Tri-Delt.

Then I was looking at this.

if you scroll down to the Delta Delta Delta one, they say Tri-Delt.

So which is it?
