These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Acceptable Lifestyle Targets: The main trio all lived with their parents when the show started. While this was never truly made fun of, it was considered "pathetic," and used to show that the trio lacked drive each in their own way.. Sam was purposely encouraged not to try to hard by his parents (who assumed he was going to be taken to hell for their sins), Sock is lazy, and Ben was too weak willed to get out from under his mother's thumb. All three overcome this when they move out halfway through the series and get an apartment together.
Acceptable Targets: There's a portal to Hell in the DMV. What do you mean that's not normal?
Evil Is Sexy: In the second season, Ben starts dating Nina, a demon. When she's in human form, you have this. When she's not, you have Fan Disservice.
When Sam performs Cruel Mercy on a corrupt Sheriff, letting him suffer by letting him live; Nina notes that she was wrong and Sam truly is evil, then promptly grabs him and gives him The Big Damn Kiss. She apologises, pointing out that she's a Demon, she can't help evil being a major turn on.
Fridge Brilliance: Sam is the only one of the Devil's children who's openly defiant to his face and willing to tell him off...which is exactly the relationship the Devil had with his own father, God.
"Funny Aneurysm" Moment: At the end of second episode, Andi jokes about being in Hell together. Then the end of the series happens and it looks like she was right.
Ho Yay: Tony and Steve aside, Sock has an awful lot of moments like this toward Sam (telling him he's never been more attracted to a man, the making out in the woods comment, always mentioning how tasty he looks, the hugging/butt slapping...), and there's even a little vice versa (calling Sock 'sweetheart', that hand-holding thing when Sam couldn't stand up well, anticipating his emotions expertly, etc). The episode "Leon" even included a little break-up-make-up plot.
Nina tells Sock she was't sure if he was gay or straight, thinking he was attracted to Ben. Although she probably just said that to annoy him, as it was in a nightmare she sent him.* Large Ham: Sock
Magnificent Bastard: The Devil, often mingling with Crowning Moment Of Awesome. Consider, for instance, The Cop: he teleports Sam into a high-class restaurant and presents him with an expensive watch and a dinner of fresh lobster, supposedly as a reward for a job well done. Then vanishes a split-second before the check arrives, leaving Sam to pay for both meals. Oh, and the watch was taken from the corpse of a recent murder victim, which makes Sam the top suspect as soon as a cop notices it.
Nightmare Fuel - Possibly in Coming to Grips after beheading a soul, Sam wants ham to eat and supposedly ham tastes alot like humans.
Romantic Plot Tumor: The aforementioned Sock-Kristen plot in the first half of Season 2, which many fans felt took up too much time.
Seasonal Rot: The first half of season two isn't liked as much, with the main contributor being the largely useless subplot involving Sock being hung up on his new stepsister Kristen, with several episodes focusing more on this than the Monster of the Week or the Myth Arc. Things improved once Kristen was Put on a Bus and Sock started acting like his old self again.
