The 'Oh My, How Lewd' meme features the character Neptune from the Hyperdimension Neptunia series, delivering a line that mockingly calls out suggestive content. The phrase became a staple in the anime community during the mid-2010s, often used as a reaction image to 'fanservice' or accidental double entendres. It captures a specific brand of playful humor where the character acts shocked while actually being amused or mischievous. Today, it remains one of the most recognizable reaction templates for anime fans, used across forums, Discord, and social media to call out anything even remotely spicy with a wink and a nod.
