Fuck 14 year old girls?
14 and 15 year old boys do it all the time.
Grown men, not so much---hopefully.
In any case, Pigshit is not a man.
One can't descend to his level of depravity and still credibly claim manhood.
Also, according to Wikipedia,
the term "fuck" and its derivatives (such as fucker and fucking) are used as a noun, a verb, an adjective, an infix, an interjection or an adverb.
I think that it makes a fine forceful expression, but it's a poor choice as a verb for coitus.
Coitus is supposed to be something that one does with somebody.
Fuck is something that one does to somebody.
A grown man having carnal knowledge with a fourteen year old girl
is, by any thoughtful standard, doing something to her.
She will unlikely remember it as a good memory.
It's totally believable that a cretin as profoundly perverted as Pigshit is capable of such despicable behavior
