A one-word description of a person who exhibits symptoms of lazyness, sloth, liberalism, or an overall entitlement attitude (i.e. one who exudes an assweasel mentality).
One who, by simply being alive, elicits feelings of hatred, anger, and an overall desire to give the Roberto a rapid onset of sudden death.
I thought that employee was going to be great when we hired him, now he's turned out to be a fucking Roberto-esque piece of shit.
I really want to rip the arm off of that Roberto-esque piece of shit and beat him to death with it.
