A Twonky is a writer or hackling who habitually refers to himself in the third person.
Instead of saying (for example) “My first book was called Happy Go Lucky Weasels,” they will say, “The first book of Lamblake Heinz was called Happy Go Lucky Weasels. There will be a reading by Lamblake Heinz in the Underpants Room five minutes from now…”
Twonkies frequently have large protruding stomachs that they use to push open the swing doors of hotels during literary conventions without having to use their hands.
