This thread has made me think of the Nac Mac Feegles (also known as the Wee Free Men, about 6” tall, tattooed blue, red haired, capable of carrying a cow, one under each hoof) - invented by Terry Pratchett - and how they were named.
” Feegle tend to have human names, usually abbreviated and with some sort of modifier (Rob Anybody, Daft Wullie, Big Aggie, No'-as-big-as-Medium-Sized-Jock-but-bigger-than-Wee-Jock Jock).”
Not to mention, Wee Mad Arthur, a feegle who works in Ankh Morpork where, amongst other things, he exterminates wasps, by going into the mpcentre of their nests, setting charges as he goes, then fights his way out before they go off.
