Have your friends singing "this is for my homies"
“Homie” is slang for friend. When someone dies, their friends will often dedicate things to them (songs, liquor pours, etc.), so Kim is threatening death to anyone that messes with her.
More specifically, Kim is referring to the hook (starts at 1:28) on the popular 1993 song “Gangsta Lean” by the group DRS.
