When you use the term 'scum sucking motherfucking piece of
shit' in relation to another
person, the subtle implication is you
don't actually like or respect them.
"You
may have saved the whales throughout the 80's Uncle Pete in your charitable life, however, there's no getting around it, in this life right now, you are a
scum sucking motherfucking piece of
shit and there's no getting around that."
