- Bishōnen: Simon Neil, especially in the video for 57.
- Broken Base: Every album from Puzzle onwards has had a much poppier edge, and brought the band to a wider audience and attention in the mainstream, leading to cries of Sell Out! and it's popular, now it sucks (masquerading as They Changed It, Now It Sucks! in most cases) from older fans who aren't happy with their new fans who only listen to their later material. This intensified after the release of their seventh album, Ellipsis, which was hailed as a success by some but criticised as bland by others.
- Ear Worm: "Bubbles." Also, "The Captain."
- Epic Riff: "Saturday Superhouse", "The Captain", "Sounds Like Balloons".
- I Am Not Shazam: Since Biffy Clyro sounds like a name, it would be easy to think that it's one person named that rather than a trio.
- Mondegreen: "The Joke's On Us" contains the most egregious example of the "our souls"/"arseholes" mondegreen since "Supper's Ready".
- Nightmare Fuel: "Tradition Feed". It's worse in the context of the album, as it's a hidden track preceded by 18 minutes of silence.
- Painful Rhyme: Happens occasionally, with the worst offender being the opening lines of "Feverish".Are we getting close? Come feel my fever
You've a right to know, I'm the one that feeds ya
- Then there's the first verse of "Flammable", which rhymes "miracle" with "miracle", and the chorus of "Biblical", which attempts to rhyme "immeasurable" with "central".
- Signature Song: "57", their most well known song among fans, and a concert staple, though it's since been supplanted by "Mountains".
- Tastes Like Diabetes: "Re-Arrange" can come across as overly sentimental. It doesn't help that Simon maintains soft, high-pitched vocals throughout the entire song.
- Tear Jerker: "Machines"
- True Art Is Incomprehensible: Their first three albums were a fusion of post-hardcore and prog rock which featured bizarre lyrics, angular riffs, frequent time signature changes and liberal use of Uncommon Time.
- Win Back the Crowd: Their radically different cover of David Bowie's "Modern Love" elicited a collective "Now that's more like it!" from fans who considered Ellipsis to be a step backwards.
YMMV / Biffy Clyro
