OMK means on my kids, idk about these other definitions
Basically when you want somebody to believe you, you can put it on something or somebody. Meaning, if you put it on your life, this means you have to be telling the truth only if you care about your life. Your friend- “Aye You have my phone? Bro I know you got that shit” you would then say “the fuck I need your phone for? Omk I ain’t take that shit”
