When a real O.G. gangsta or any or other brave soul kisses the end of the barrel of his gun and then place it on the lips of his enemy and pulls the trigger( this is only in very rare situations that this will ever occur and is the ultimate sign disgrace, note commiting this act dubes one as an O.G.
Damn Moses is a true O.G. that nigga gun kissed a little crips nigga that was tryin to phase. Note only little bitches die by a gun kiss.
