Dumb As Fuck

You know, the guy above trying to be a smartass said there instead of their when referring to someone's idiocy. So really, the guy above is dumb as fuck.

The guy above: People still use it incorrectly though, showing there complete idiocy when they cannot correctly use the most versital word in the English language.

Me: Wow, you can't spell versatile, AND you said there instead of their. You are dumb as fuck.

dumb as fuck

One of the only grammatical instances where the word "fuck" cannot be used. "Fuck" can serve as an adjective (your fuckin' stupid), verb (I want to fuck you), or a noun (you are one miserable fuck). However, when used as a noun, "fuck" is not plural by itself, like the words 'shit' or 'moose'. Fuck can only be plural when an 's' is attached (fucks). People still use it incorrectly though, showing there complete idiocy when they cannot correctly use the most versital word in the English language.

Correct: "You guys are dumb fucks."
Incorrect: "You guys are dumb as fuck."
