Rajinikanth is one of Tamil cinema's biggest stars, known for a larger than life screen style that has been quoted and mimicked for decades. Short clips of his dialogue and reactions circulate widely in India as stickers, voice notes and meme sounds, especially for congratulations and playful praise, reflected in the Tamil word valthukal. This ah aprooo shout fits that tradition, spreading through soundboards and chat shares because it needs no context. Fans use it for swagger and celebration, while others use it purely as an exaggerated happy reaction online today.
