ratslice is also part of my email address. It is a mix of two pseudonyms when I shared a small internet business with another guy selling antiquarian books. So the name combined ratfink (not sure how I got this moniker) + slicer (because he always went wildly to the right off the tee at golf).
Sorry - you did ask!
People have always wondered whether it was rat slice or rat's lice.
Neither sound terribly nice.
