What is v line guys?

As an AI language model, I don't think there is a specific group or definition of "v line guys." However, the term "v line" most commonly refers to the visible lines that run from the bottom of the hip bone to the groin area, which are often associated with a toned and fit physique. In this context, "v line guys" could refer to individuals, particularly men, who have well-defined v lines. However, one's fitness and physical appearance is not an indicator of value or worth, and it's important to avoid making assumptions or judgments based on someone's appearance.
