"could of"
Fucking enrages me so much. It's more than a simple mistake. People have to actually utilize their feeble minds to write "could of". The lack of brain activity to replace "have" with a word that isn't even a verb is staggering. Any native English speaker who is half alert should have their brain trigger numerous alarms during the process of typing that out and yet I see it several times a month. I try to remain optimistic but it just beats me down when I see this. It becomes clear that this world is filled with illiterate dullards unable to differentiate language from some meaningless blob of noise.
