The 'That's My Purse! I Don't know you!' meme originates from the Season 6 premiere of the hit animated sitcom King of the Hill, titled 'Bobby Goes Nuts.' In the episode, Bobby Hill enrolls in a women's self-defense class and learns to incapacitate attackers by kicking them in the groin while shouting this signature line. The scene became an internet sensation due to Bobby's unexpected aggression and the hilarious absurdity of his delivery. Today, the template is used to represent fierce territoriality, over-the-top reactions to minor inconveniences, or as a humorous way to tell someone to back off.
