Your question does make sense, and the answer to both of your questions is yes. To fully discredit the argument, we would want to show an actually counter example- that is we would need the actual boy named sue. However to weaken an argument we don't need to fully disprove it, so a statement like "it's not impossible for a boy to have a name like sue, which is typically associated with girls." Would suffice. Effectively, if we want to completely disprove a premise we need a counter example or a statement showing it is false, but to weaken all we need to do is to cast doubt on it, not to fully disprove it.
