The note at the beginning of Welcome to the Black Parade by My Chemical Romance. This note triggers emos, even repressed ones. If you play this note in front of any emo they will die.
Random Person: "I'm gonna g note you."
Emo: *Dies*

The beginning to the song "Welcome To The Black Parade" that makes every emo lose their shit while crying eyeliner.
Non-emo friend: Hey I found this really cool song!
Repressed emo: Cool, what is it?
Non-emo: *G note plays* Welcome To The Black Parade!
Emo: *crying eyeliner*

The G note on a piano is highly important to punk rock/emo rock fans who listened to My Chemical Romance. This note is the opening note to one of MCR's most famous songs, "Welcome To The Black Parade" and while this song is not sad in itself (it's actually very inspiring and upbeat) it saddens the MCRmy/Killjoys because the song was the anthem for that fan base.
If you play it they may cry or get really sad (some over exaggerate and lose their shit so be warned)

Also they will probably mention Geesus/Gerard/Gee at some point.
"Dude, what's wrong?"
"I got g-noted and now I really miss MCR."
"Really, Cas?"

The one fucking note that starts "Welcome to the Black Parade" and will cause every existing emo, ex-emo, or repressed emo within a 20 mile radius to lose their shit, scream the lyrics, and cry with the edge and angst of a million 8th graders.
I fucking swear Rylan do that shit again and you're getting G noted
