Fongs in thongs 

The natural attire of Jay and Matt Fong is the thong. From this common wardrobe selection, the colloquialism "Fongs in thongs" developed in the late 1990s.
Variations: Fongy thongy, thong Fong, etc.

I sure am glad I signed up to help with Rainfest because I got to see Fongs in thongs.
