An unusual word, in that it is both an adjective AND a noun. You can not only BE a "Dirtydog", you can also act LIKE a "Dirtydog"
To act in a Tiresome fashion, or to moan about everything and everyone that isn't to your taste or agrees with your opinion.

or
"Andy, don't act like a Dirtydog mate, it doesn't fucking suit you"
