Friends Rent Control - Mostly averted, as Ruxin and Andre at least are both relatively wealthy. Though Kevin's income as an assistant district attorney is probably modest, Jenny is a real estate agent, justifying their house between them. This only leaves Pete and Taco; Taco's home is a disaster area and Pete has a decent apartment, appropriate for a single man in Chicago.
There have been frequent references to Taco being "pretty much homeless".
Gainaxing - In episode two, "The Bounce Test", various circumstances force Ruxin to find a "porn loophole": an underwear website featuring video demonstrations of their products being used by well-endowed joggers.
Genius Ditz: Taco is fairly talented musically, but too wasted to do anything else.
Gilligan Cut - Kevin promises that he, Jenny, Ruxin, and Sofia won't talk about Pete and Meegan's breakup at dinner. Cut to...
Jerk Ass - Everyone to some extent, though Ruxin and Rafi are probably the worst.
Karma Houdini - Though everyone gets away with things sometimes, like when Kevin lost his virginity to Shiva in Pete's mom's car, left the condom behind, and kept the incident a secret for years, only revealing the truth after Pete had returned the favor to the person he THOUGHT guilty of the offense, losing an amazing job offer in the process, Taco rarely receives any sort of comeuppance for his outrageous behavior. Possibly justified, as they are used to his antics and/or feel guilty over making him smoke pot when he was 8, turning him into the massive stoner he is today.
My Friends... and Zoidberg - A nonverbal example. After Ruxin wins the championship in the finale of season 2, he tussles with Andre for possession of the trophy. It ends up sailing off a fire escape and smashing through a car windshield. At that point, Pete arrives in the cop car he now drives, takes control of the situation, and whisks everyone away... except Ruxin, who they gleefully leave behind to deal with the furious owner of the car.
Before the season 3 draft, Ruxin beckons the rest of the league to Andre's balcony.
Ruxin: Gentlemen. Taco.
Noodle Incident - While never verbally mentioned, observant viewers can see that Taco has actually won the Shiva Bowl once. Due to his complete ineptitude with fantasy football, one can't help but wonder how this could have possibly happened.
No Social Skills: Andre, and then some. It's heavily implied the reason he never leaves the league is because these are literally the only people who will talk to him.
Obfuscating Stupidity - Taco, if Ruxin and Sofia's anniversary is any indication. He shot behind the scenes footage of their wedding and saved it for ten years, using it in what seems to be a very lengthy Xanatos Roulette, or even Batman Gambit, to incriminate and embarrass not only Ruxin, but Kevin, Andre, and Meegan as well, at an anniversary party he manipulated Ruxin into throwing in the first place. When his plan culminates in Ruxin having to eat a piece of wedding cake that had been thrown onto a bathroom floor, Ruxin even calls him "an evil genius."
In an interview the Producers confirm Taco is far smarter than given credit.
Ever since the events between season 2 and 3, Taco has been shown to be far less clueless, much more deliberate in his actions and just flat out more intelligent.
Obnoxious In-Laws: Kevin and Taco's mother, who constantly judges Jenny and condescends to Kevin.
Once an Episode: It's fairly inevitable that something shown or mentioned in the first scene of an episode will play into the punchline at the climax.
One of the Boys - Jenny, though a somewhat unusual example—she's not really a tomboy and certainly is feminine. She's just really good at fantasy football and can engage with and challenge the guys on their own terms. She also seems more comfortable with the boys than with Sofia, who she finds irritating, though notably Sofia is the only female (other than her own daughter) that viewers see her interacting with on even a semi-regular basis.
Running Gag - Shivablasting, Eskimo brothers, Andre looking like Nosferatu, vinegar strokes and Mr. Mcgibletts.
Upper Class Twit: Andre is essentially this in practice; while he does work for his money, we never see it onscreen and it doesn't seem to interfere with his multiple hobbies.
With Friends Like These - Even without the constant volleys of insults and pranks, every single member of the League will manipulate and betray any other member for even the slightest of advantages in their fantasy football tournament. Except for Taco, who is to stoned to know what manipulate means.
