Name for a bitch, cunt, fat chick, whore, skank, or any other derogitory female slang. Specifically for girls who act like they can get all the men they want but really can't.
Origin :
A girl with a shitty name like Alessandra acts like she's the shit but it really Fuck-less.
Hence, Fucklessandra.
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.
