The 'Boner Alert' meme is a staple of internet reaction culture, typically used to signal an exaggerated or ironic state of excitement or attraction. Often featuring loud sirens, flashing lights, or characters in a state of shock, it draws inspiration from early internet 'alert' tropes and shock humor. While it originated in more explicit circles, it has evolved into a mainstream ironic tool used to mock 'thirst' posts or suggestively funny situations across social media platforms like Twitter, Discord, and Reddit to highlight moments of undeniable awkwardness or attraction.
