The 'Boop' meme is a lighthearted internet phenomenon centered around the act of gently touching an animal's nose, often referred to as a 'snoot.' This wholesome trend gained massive traction on platforms like Reddit, Instagram, and Tumblr, evolving from simple photos of pets into a universal symbol of affection and playfulness. The term itself is an onomatopoeia for the sound made during the touch, turning a simple physical gesture into a widely recognized digital expression of cuteness. Today, the Boop meme is used to highlight adorable moments, celebrate pet ownership, and provide a positive 'palate cleanser' for users scrolling through their feeds.
