ZK effect
The sudden and intense experience of falling deeply attracted to someone (specifically with initials ZK) because of their unique personality, humor, and unapologetic weirdness. It’s often accompanied by the realization that you’ve never felt this kind of attraction before. As it progresses, you start wanting to be exactly like them—subconsciously adopting their humor, personality traits, and even the way they talk.
