I'm so glad "Snow Job" was actually about what it means, since it is such a great term I've had to drop from my vocab because everyone always assumes it's about BJs. I mean, I'm me, so it's not the craziest assumption, but as a con artist, I really like how you blended the meteorological in (I think 'low pressure' is a great image), and maybe more could be added? I do think there's more to wring from this, and it would definitely be punchier with some extraneous text removed ("so well and thoroughly", "how to accomplish", etc). I want to know more about the person who's being snowed, and what's currently making the lie necessary/fun/customary.
