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.
Big In Japan: So big that after their dissolution following the release of Pinkerton, it led the band to reunite when in 2000, Fuji Rock Festival offered Weezer a high-paying gig. Their popularity in Japan is addressed in "Across the Sea" and the liner notes of the Lion and the Witch EP, which contain letters from Japanese fans written in Gratuitous English. Their influence can be seen in the sound of such bands as Asian Kung-Fu Generation.
Not only that, Rivers's wife is Japanese and the family spends part of the year in Japan.
Broken Base: Of course, the most famous are the "Blue Album and Pinkerton only" crowd, but there's also a significant amount of the fanbase who likes everything made before Make Believe, those who only like the stuff they did Make Believe and afterwards, and those who like everything they've ever done. None of these fan subdivisions get along too well.
The music video for Photograph shows home made clips of what the band did during the Green Album Tour. Somewhere between clips of Rivers playing soccer and everyone playing pranks on their new bassist, the band is shown performing on stage as Jack Black and Kyle Gass of Tenacious D barge onto the stage and join in.
Adding to Blue: all guitars on the album were recorded by Rivers. Yes, all of them.note The band fired Jason Cropper during the sessions and there was no time to have Brian Bell add to them, so Rivers did it all alone to get it done quicker, since the album was already behind schedule. Brian did add backing vocals though, and was credited for rhythm guitar in the liner notes. He disagrees with Rivers' story and claims he really played guitar on the album.
Epic Riff: "Burndt Jamb", "My Name is Jonas", "Island In The Sun", "Undone (The Sweater Song)", "Only In Dreams", "Tired Of Sex", "Say It Ain't So," "Hash Pipe"
"Funny Aneurysm" Moment: The B-side "Mykel and Carli" is named after two girls who befriended the band and ran Weezer's fan club. The once bittersweet song became a pure Tear Jerker after they died in a car crash, as the song includes the lines Then the schoolbus came/Took my friends away. It's also notable that the song's A-Side, "Undone (The Sweater Song)", featured Mykel's speaking voice.
Memetic Mutation: While trying to interact with fans during the Maladroit sessions, Cuomo had an infamous outburst when he described the universally acclaimed "Only in Dreams" as "GAY! GAY! DISNEY GAY!". Since then, Weezer fans sometimes use the term "Disney gay" to either disparage latter-day songs they consider "cheesy" or to sarcastically admit they like a song.
Misattributed Song: They've had a lot of songs misattributed to them, but one particularly interesting case is "Teenage Dirtbag" by Wheatus, since they would later perform a Cover Version live. And the band themselves are guilty of associating a song with the wrong artist in a lyric from "Heart Songs": "Debbie Gibson, tell me that you think we're all alone" (Tiffany was the eighties teen idol who famously covered "I Think We're Alone Now", not Debbie Gibson).
Narm Charm: The hilariously yet lovably misguided use of hip-hop slang scattered throughout the band's discography. Its use in "Buddy Holly" and "El Scorcho" is at least somewhat more noticeably ironic.
Painful Rhyme: It's Rivers Cuomo, so there are plenty, but one unfortunate example from "Troublemaker" goes "Marrying a biotch, having seven kiods..."
"Back to the Shack" tries to rhyme "dad" with "am".
Vindicated by History: Pinkerton. Initially blasted by critics for being far darker than The Blue Album, the album has since come to be considered one of their best efforts and one of the best rock albums of the 90s.
