Final answer:
The eye makeup trend involving a sideways "V" at the outer corner of the eye is called the cut crease.
Step-by-step explanation:
The eye makeup trend that involves using your pencil to create a sideways "V" at the outer corner of your eye is called the cut crease.
In a cut crease look, the emphasis is on defining the crease of the eye by using contrasting colors. By creating a sideways "V" shape with your pencil or eyeshadow, you can achieve a sharp and dramatic effect.
For example, you can use a lighter color on the eyelid and a darker shade in the crease, drawing the sideways "V" with the darker shade to create a striking contrast.
