curious

Can anyone explain why my pizza receipt would have the word uroboros printed on it?

I assume this is some reductive modern spelling, possibly with a meaning change, like esthetician, which word unreasonably enrages me. Is this an endless snake that refers only to pizzas?

ETA:

I am pleased that my friends immediately decided it was some kind of come-on. It was computer-printed, like the rest of the receipt, so it would have had to be someone at the other end who liked the voice of the caller, which was inlandsea. Other possible targets of herpetological admiration include stitchinmyside, who paid for the pizza.

I dunno. An ouroboros seems a little onanistic to me.
