(n) An individual, typically male, who takes a disproportionate, erotic interest in mildly titillating content (e.g. an attractive girl's face, any amount of cleavage, or a photograph showing side boob
). It is assumed that this is because the individual lacks sexual experience, thus rendering that content new and exciting. Perpetual horniness is also a common turbovirgin trait.
Dude, calm down and stop being a turbovirgin. It's cleavage, not a striptease.
