A Phase Laser is a woman or babe that instantly turns a guy on to an extreme level. Phase lasers are somehwhat rare and should be observed at a distance so that no harm can come to the male observer. Like love at first sight, a phase laser is similar in that she will in no doubt attract all the male attention in a 500m radius. When her pure gorgeousness and beauty along with perfection present itself, you will know that she is a true phase laser.
The term phase laser is derived from theoretical physics, in that a male will change what state(or phase) he is in when he catches a glimpse of phase laser.
WARNING do not over-dose on phase lasers, this can lead to extreme mental illness, and phase lasers should always be taken seriously. A flase phase laser (due to observing at a further than normal dustance) can cause blindness at close sight.
