An abrasion, sprain, cut or other injury caused by excessive use of one's finger(s) while reading a nook or e-reader which inhibits or hinders the use of one's e-reader.
My sister called and complained that she can't finish the book she was e-reading because she hurt her finger. I said "Dude, you've got Nookfinger"!
