A class of non-gang related graffiti/tagging left by a fuckwad. Often resembling the scrawl of a young child, fuckmarks are distinguishable from street art in that they posses a distinct lack of creativity and artistic talent in both style and message.

In many cases involving fuckmarks, the the fuckwad, when confronted may be delusional and claim to be a talented artist in another large city such as New York or Los Angeles.
I walked down the alley this morning and it was full of fresh fuckmarks.
