Napoleon Dynamite is like if Superbad was nothing but that scene of Michael Cera singing "These Eyes" by The Guess Who. Just 100% cringe, awkward interactions between the main characters. Like an inside joke that literally nobody is meant to get, even the people "in" on the joke.

Honorable mentions: Nacho Libre (similar in its randomness), Wayne's World (a classic) and Road Trip (similar to Superbad in its frat humor).

Pineapple Express
Hangover movies
Knocked up
Project X

Not the best of tips, but that’s what I was thinking off

I really liked the film Booksmart, which is kind of like a genderswapped Superbad, definitely worth a watch.

It might not be that similar but I remember after I watched superbad I watched Eurotrip. The movie might've not aged as well as I remember though, I last say it when I was 15 and thought it was hilarious.

Still quote some stuff to this day

Youth In Revolt

I have no shame admitting I liked this film, the only other alike that I have watched is Project X, definitely gonna save this post to check out others lol.

Role Models is in the Superbad neighborhood and filled with all-time quotables.

To me, Superbad falls under the “one night in high school” genre.

It depends on what exactly did you like about the movie?
