it is for crossing 

Another way of saying "let's go."

It originated late one night when a teenager was having trouble speaking but wanted her friend to follow her.

Relates directly to a traffic light giving you the right of way, but can be used in any context.

Usually said on its own and not in conjunction with other words or sayings.

Carly: "It is for crossing."
Casey: "Oh, ok." <they both walk across the street>
