piece of shit kid
The kind of child that makes the lives of others more difficult. A child whose swift demise (preferably through shark attack, although other methods of disposal would be suitable) would have societal benefits.
Gentleman, I think we can all agree that this kid is just a real piece of shit. I mean, the class is a good class, but fuck that little piece of shit kid Carlos. The definition of a little shitty shit. What a shitty kid. Fuck that kid.
