A monogrammed yoga mat.
I do not think there is anything on this planet that is more "me." AND they have a whole sorority Greek-letter section. This ADPi would settle for a more subdued diamond shaped monogram on blue and white (that's pi-tastic enough for me). Props to Elizabeth for the tip--Pi love and OBIC, babe.
Now if only it fit in my luggage...
