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.
Alex claims to have seasoned Lester's popcorn with his own semen. He claims to be joking, but with Alex it's hard to tell...
The second season trailer reveals Kevin is squicked by sex with zombies, while Lester and Alex are squicked by sex with someone covered in leeches.
Unfortunate Implications: Alex is only interested in another guy because he snapped and isn't right in the head. A lot better when you realize it's not a matter of gender so much as proximity; Lester is just conveniently close.
Awesome Moments: S1 finale when Val, having had enough of Sadie's shit, dumps a bowl of punch all over her, then delivers an Ironic Echo of something Sadie said a minute earlier.
Ming gets two in S 3 E 9 - first, she punches Becca in the face after her crossing the line with getting Fred Wu in trouble at school, and then later having the rest of the "Asian Mafia" actually bow to her for what she did.
Matty telling off Eva in the mid-season premiere of Season 4.
Hollywood Pudgy: Fan reaction to Ashley Rickards' weight gain between seasons 1 and 2.
Seasonal Rot: Set in starting season 4, since creator Lauren Iungerich left the show.
Tear Jerker: When Jenna sees Matty kissing another girl in the hot tub. Then one season later when Jake sees Jenna and Matty kissing in her bed. The look on their faces in both scenarios gets you.
Jenna singing the lullaby to her mom can definitely count as one of the (if not the) biggest tearjerking moments in the series thus far.
The Woobie: Jenna, and to a certain degree, Lissa.
It's hard not to feel bad for Lacey after the whole school reads Jenna's blog and starts to call her nonstop with hostile words.. Could be Jerkass Woobie for some, especially considering she really should have known better than to make it open for the public to read and just assume that nobody from her school would ever come across it.
