- Ear Worm: Quite a few to be found on their album. Try getting the whistled hook from "Pumped Up Kicks" out of your head upon hearing itů it's not easy.
- Estrogen Brigade: Each member of the band brings this in different flavors; Mark Foster has an Adorkable quality to him, Mark Pontius is the cute, blonde one, and Cubbie Fink is the brooding, dark haired hottie.
- Lampshaded in the "Call It What You Want" video; throughout it, Mark (Foster) is shown being stalked by a horde of rabid teenaged girls wearing shirts that spell out "Foster" collectively.
- Face of the Band: Mark Foster, seeing as how the band is called ''Foster'' The People.
- Harsher in Hindsight: "Pumped Up Kicks" is about a guy who acquires a gun and plans to shoot people for it. This becomes much harsher in hindsight, due to the movie theater shooting in Aurora, Colorado, and especially due to the Sandy Hook Elementary School shooting in Newtown, Connecticut.
- Not really that harsher. It was written with Columbine in mind, so it's kind of Exactly As Harsh In Hindsight.
- Nightmare Fuel: "Pumped-up Kicks," being known for its Lyrical Dissonance about gun violence, this troper was reminded of the Columbine High School Massacre, because many peoples' comments wondered if this is what the song's about (among other shooting attacks); due to this, I've done a lot more of research on the massacre... and now will never be able to listen to "Pumped-up Kicks" again without picturing Eric Harris' & Dylan Klebold's school shooting taking place.
- Mark Foster was in high school when Columbine went down. This troper (one year older) can assure you: There's pretty much no way he wasn't thinking of it when he wrote the song.
- There's an available instrumental version of the song. At minute 1:02, right before it gets to the chorus, you can hear a brief, distorted voice. It's hard to understand what it says. To me, it sort of sounds a bit like, "Leave here when you die." What's creepier is that I - nor even many of us - noticed this bit in the original! Worse, it sounded like people were shouting during the chorus... turns out it was rhythmic clapping.
- Crosses over with HarsherInHindsight when the song is taken in context with the shooting at Chardon High School.
