A reddit kid, some phrases they say “dat boi “smol bean” “oof” “do you watch call me carson?” Their whole personality is revolved around self depricating jokes and doing weird poses

The most out-of-touch, unfunny and awkward people you can find at any high school. They frequent Reddit and constantly regurgitate old memes they hear on the website. Can also be seen in anime or video game-related events and clubs, as well as the band room.

A "band kid" is a high school kid who's entire life revolves around being in marching band
They're personality is that they are in marching band
They're often total spergs incapable of talking about anything other than band and internet memes
An important note is not all kids in marching band are band kids but because there is enough of them to form an annoying band kid culture at almost every high school in the America it's fair to assume most are

The annoying kid that squeezes out a meme in every sentence.

The term ‘band kid’ means someone that basically lives and breathes a certain selection of memes. These types of ‘memes’ are usually deep fried, t-pose, bruh, 🅱️, thicc, Soviet Russia, roblox oof sound, 🅱️eter griffin, big chungus, Alexa play despacito, liek if u cride, etc. ‘Band kids’ stereotypically like beating it to Pokimane, watching Call me Carson, playing Minecraft, listening to monstercat, watching Reddit text-to-speech videos, PewDiePie, and a bunch of other weird shit. I hope that explained it.

One who is in the high school band, and more specifically, the marching band. Probably some of the biggest perverts you will ever happen upon, a band kid's life centers around marching band.
Their life? They have none because it consists entirely of marching band.
It is worth it though and they love every minute (That they're not hating with a passion, such as parades.)

Most wouldn't trade it for the world.
Roll stepping your way through band camp, 'band bus' rides and the shenanigans that go on, competitions and practice.
This is our life.
