A person who (usually male) isn't responsible for themselves, has accomplished
nothing in life, is lazy, entitled and selfish, but thinks they'
re just absolutely fucking genius. A scrub
will feed off of you emotionally and financially, convincing you first that they've just
cut a bad deal in life but are getting back on their feet and at first you can't believe somebody so nice and smart is always being treated so mean. Then over the course of months or years, it dawns on you you're being played for a sucker.
