An all-too-obvious way to say "Fuck off" on a vanity license plate when one thinks the DMV won't know what it means.
Someone has "FCOUGH" on her license plate. Soon she'll have a complaint letter sent to the DMV!

An alternative way to type fuck up. When someone is a big ass loser they are a f'cough, like the word hiccough (also spelled hiccup).
"No, I decided not waste any more of my time with that loser! He's a total f'cough!"
