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.
Look at that phase laser in that shop!
That phase laser in the green hoodie is phasy.
