The 'Why Do Good Girls Like Bad Guys?' meme originates from the 2011 song 'I'm Not a Vampire' by the post-hardcore band Falling in Reverse, fronted by Ronnie Radke. The specific line gained massive popularity on TikTok in late 2018, where users would perform lip-sync transitions between a 'nerdy' or 'good' persona and a 'rebellious' or 'bad' persona. This trend turned the song's lyrics into a versatile cultural shorthand for exploring dual identities, social stereotypes, and the perennial mystery of attraction. Today, the template is used both ironically to poke fun at the 'edgy' aesthetic of the late 2010s and earnestly to create humorous comparisons between different personality types or fictional characters.
