I have no idea what it means but I would assume it means "sexual liberties" or something... The purpose of the image was to show that those types of people do not relate at all with normal, hard working people.
And I would say: Mission accomplished.
After all, from whence do these unruly mobs materialize - especially on weekdays during what most of us would consider "normal business hours"? It would appear that the majority of them either do not work, are supported by wealthy trusts and foundations fueled by Liberal Guilt, or are simply enabled by indulgent and negligent parents.
