I remember the phrase being used by Eric Idle in "Splitting Heirs" (I think) describing his sexual preference. "I'm buysexual. I need to buy sex". A sort of pharmaceutical look with a $ sign instead of the usual ®.
Every now and then I make myself a T-shirt as some sort of a "walking billboard" statement or just for the sheer joy of making it. I make only one piece each and they are not for sale yet. (Orders are not available.) This is just a test drive and T-shirts will be available in due course.
