A person who hacks rides. Slugs are people who need to go somewhere faster than the bus will take them, but don't want to wait for/pay for a cab.

Hacking is basically modified short-range hitchhiking, and is accomplished by standing on the curb, extending one's arm up at an angle, and pointing downwards repeatedly until a car stops. Pricing and destination are then negotiated. May be specific to Baltimore.
I picked up a slug the other day on the corner and took him to work.

Slugs are people who anonymous ride-share, with drivers who need an extra body or two to get into the high-occupancy lanes.

Slugs line up for a free ride at designated spots such as commuter parking lots, street corners, and bus stops where drivers use them to get in high-occupancy lanes to make commuting for the driver faster.

Slugs is reported to come from bus drivers, who were waived off by people at bus stops who were waiting to be picked up by commuters. The "slugs" term was orginally used as the term for a counterfeit coins. In this case it is used for "fake" bus riders, neigher of which pay.

The slugging process works like this. A driver comes up to a line of people going to work or the city and announces his destination to the "caller" who is the person who is at the head of the line. The "caller" then relays the destination information to the slugs behind, to find the persons in the front of the line going to the same place.

There is a slug etiquitte, which includes never giving the driver your name, no eating, no drinking, extremely limited sell phone use, no messing with the music, no messing with the windows, and no heavy pollical, religious debates etc.

Counterfeit coins used in subways and buses are also known as slugs.
Don't you hate being on highway with bumper to bumper traffic, and see these crazy car poolers in the high occupancy vehicle lanes zoom by.

No, when traffic is really bad I pick up a couple slugs. I think of it as carpooling lite. Where you have the freedom to do what you want when you want, fast, on fast highways.

But do you really want to have a bunch of strangers in your car?

When you commute with slugs there is a certain amount of etiquitte that you don't find with some car poolers, who think they have the same rights in your car as they do in their car.
