Fuck is a command. Someone pisses you off, you tell them to Fuck off.
Simple. Fuck is an expletive, as in Fuck me, Fuck you, Fuck this. Fuck
is verb and emphasis, like Fucking jerk, or Pass the fucking salt. Fuck
gives you a way to tell someone they’ve overstepped the line, Shut the
fuck up, Go fuck yourself.
Fuck is creative and immensely satisfying. Telling someone to Go take a
flying fuck (at a rolling doughnut) will make them step back a pace.
Fuck expresses and emphasises confusion like no other word, What the
fuck, What the fucking fuck?
Fuck is a word for a night in the pub, Fucked again. Or for those who
give you grief while you’re there, Fucktards and Motherfuckers. It can
be used on the way home, or in the morning, to great and colourful
effect, My God, I’m never fucking drinking again.
Fuck is rebellion, teenage or otherwise, Don’t fuck with me, Don’t do me
any fucking favours, Fuck the system, Who gives a fuck?
Fuck expresses depressive anger, Fuck the world, and equally, the
encouragement that’s its opposite, Don’t get fucked up, fucked over, She
isn’t fucking worth it.
Fuck expresses confusion, Who the fuck are you, What the fuck is this,
You’re fucking kidding me. It expresses exasperation, You dumb fuck.
With the right character, Fuck is a word that adds an underline to
almost any emotion, that exaggerates speech and reaction, that can be
put fucking everywhere, to fucking enhance anything, and still make
fucking sense.
Fuckers.
