I am now actively working on a new edition of The F-Word. I've just posted about the project on the Strong Language blog, with examples of new entries & a list of things I'm actively looking for. Please send me suggestions, quotations, &c.! And please share this!

"fuck buddy" was already in, with a first quotation from 1973 (1972 for "fucking buddy").
"fuckwad" was also already in, from 1974.
Cory Doctorow used "fucknozzle" in 2012, but there's not enough other evidence for me to have drafted an entry for it.
