“You’re the Worst” is the second new comedy FX is premiering Thursday night (along with “Married”) and is by far the best. Both series are about relationships, but they’re very different, intentionally so.

“You’re the Worst” is about twenty-somethings, primarily Gretchen (Aya Cash) and Jimmy (Chris Geere), and is purely sarcastic, sneering and obscene. Through two episodes, it’s also incredibly funny and heartfelt.

After Jimmy gets kicked out of his ex’s wedding for drunkenly berating her, he meets Gretchen outside holding a stolen blender from the same wedding. They form a strange and antagonistic, I-hate-everyone bond.

The two spend the night having raunchy sex and telling each other their worst traits and digressions. Here, they form a deeper bond that neither wants to admit.

As the excellent pilot (written by showrunner, and “Weeds” scribe and “Orange is the New Black” co-executive producer, Stephan Falk) unfolds, we learn a lot about our two leads and how they might just be perfect for each other — because they’re both unpleasant people. I like how “You’re the Worst” holds nothing back with its comedy — think a rom-com version of “It’s Always Sunny” — while managing to create a romance with some heart.

The two leads deserve a lot of credit. Cash is particularly wonderful as a no-nonsense woman who’s only scared of opening her heart. She always has the perfect comeback, but conveys a subtle vulnerability. Geere is also strong, feeling like Hugh Grant’s lovable cad from “About a Boy.”

But the main attraction here — which will surely turn off some — is the series’ outlook on “relationships.” It’s not a bleak one; only honest (like Jimmy and Gretchen) that relationships rarely last forever. Knowing one is doomed enables both involved to revel in its immediate pleasure and not worry about the future.

The only tiny issue I have with “You’re the Worst” is longevity. Once Gretchen and Jimmy start dating and inevitably screw it up, where does the narrative go? I’m not sure, but so far their antithetical meet-cute and budding romance is pure (and disgraceful) bliss.
