A vogler is a person (usually a man) that frequents a beach/nude beach, pool, bath house and other places where there are people enjoying themselves in less clothing or in the nude. One give away of a vogler vs. a random wandering person is that a vogler
will many times be seen at the beach in normal clothes such as jeans and a
t-shirt while wandering and lurking around the place and subtly (or not)
will gawk, stare and "vogle" around people to visually feast on.
There are many types of voglers and varying aggressiveness. Some
will wander around aimlessly looking lost until you notice that they have walked next to you several times while continually staring. Other voglers
will find a nice spot in some brush or a public area such as
water fountains and
will use this as a lookout where they can enjoy the view without bothering others. The worst type of vogler is one that
will find a place to be near you and
will stare and gawk with no shame or self-awareness sometimes going as far as sneakily taking pictures with their smartphones.
