Note: Taunts must be under 1mb in size, and less than 6 seconds long.
Right click Garry’s Mod in steam, go to properties
Local files -> Browse local files
Go to the “garrysmod” folder, then “data”, then “harrysmod”, then “taunts”
Place your taunt in here and name it “taunt.mp3” (probably case sensitive)
IF THIS DOES NOT WORK, NAME IT “taunt”. THE FILE FORMAT CAN COUNT IT SEPARATELY SO IT CAN READ IT AS “taunt.mp3.mp3” AND NOT WORK.
Load up the game, join the server, go to the VIP+ tab and press “Upload custom taunt”
Wait a few hours or so for a staff member to approve the taunt
Done! Press F4 to play the taunt in an area around you, and when you kill another player, they will hear your taunt.
