A child who is conceived through a
good fucking as opposed to an
act of love. Often used after the word bastard to strengthen it - bastard fucklet - , thereby implying the child was not only conceived out of wedlock, but also from a loveless screwing - a
good fucking.
Could just be a simple insult that a joe six-pack might shout at his child:
Go get me another beer, you little fucklet.
If that same child scratched his father's Pontiac Firebird.
You scratched my Firebird - I'm going to kill you, you little bastard fucklet.
or, it could be used as defined
Johnny's mama was picked up at a bar and, they screwed so hard the
condom broke. Looks like
Johnny is a little fucklet.
