To be so insanely tough and merciless. Your average street tough might be hard. But Arnold Schwarzenegger as John Matrix in his 80's hit "Commando", and John Rambo played by Sylvester Stallone are examples of "Hard as Fuck"
Col. John Matrix kills 200 people with an enormous machine gun with his pecs bouncing with recoil. He is hard as fuck.

To be mentally strong. Nothing will phase someone who is hard as fuck, not death, hard times in the hood or someones words.
Examples of the word Hard as fuck is best shown by scarface, Mike tyson, Tupac, Pablo Escobar and the entire Dumas family. Nothin stops em no ones got shit on em. Complete Bosses.

No Fear, No Remorse, No Regret and take no shit
Like in Dawn Of The Dead.Trapped on a bus surrounded by fucking zombies with nothing but a single bullet and a propane tank. You shoot the tank and blow yourself and all those fuckers straight to hell. Thats Hard As Fuck!
