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.
