The phrase comes from Kevin Durant's NBA Most Valuable Player acceptance speech in May 2014, when he thanked his mother Wanda Durant for supporting his basketball career through difficult years. The line was clipped and shared widely on social media, where it quickly became shorthand for praising someone selfless behind another person's success. It spread beyond basketball into birthday posts, Mother's Day tributes and sports edits, and it remains popular because it works both sincerely and playfully, giving creators a ready-made way to say thank you with real emotion.
