Sororities in Tonga?

This is a shout-out to all my Gamma Phi Beta friends. Tongans wear the most random t-shirts, and half the time they don't even know what they mean because they're in English, slang is involved, there are innuendos, etc. Example of this: I recently discovered that my 11 year-old neighbour girl has a Gamma Phi Beta tshirt. It's for intramural sports. On the front it says "Gamma Phi Beta IM Sports" and on the back it says "Always looking to score..." I'm going to go out on a limb and say that my neighbour doesn't fully grasp the joke (and I'm certainly not going to explain it to her!).
