Definition of "fucker"

You didn't tell me that this was for children. I hate children. I'd raise money to have the little fuckers put down. I want me money back!

1994, John Hodge, Shallow Grave, spoken by Alex Law (Ewan McGregor)

Never stood a chance. The poor fucker was cooked.

2016, Allan Smith, Consequences, page 326

I wanted to look up velleity and quotidian and memorize the fuckers for all time, spell them, learn them, pronounce them syllable by syllable—vocalize, phonate, utter the sounds, say the words for all they're worth.
