The "That's my son" meme originates from a playful yet heartwarming trope found in both real-life and media: the sense of unstoppable pride a parent feels, often ignoring any surrounding chaos or questionable decisions made by their offspring. In this meme, the character is humorously depicted as a gorilla, known for their strength and protective nature, but here portrayed with an unexpected soft side—showing pride in their child's antics, no matter how reckless. This concept taps into the universal theme of parental pride, and it likely gained traction due to its relatable, albeit exaggerated, representation of parental love and the humorous situations we find ourselves in when observing the choices of loved ones.
