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.

the word "slug" has a variety of definitions:

1. a bullet
2. a shot (of liquor)
3. to punch or knock unconscious

these definitions can often be found in hard-boiled detective fiction popularized by writers such as Raymond Chandler and Dashiell Hammett in the 1930s and 1940s.

A west point cadet who does not play on a varsity sports team. Characterized by napping (taking slugnaps) during every free minute available, usually from lunch to dinner, because they stayed up till 3am watching youtube videos and facebook stalking the night before.

They also frequently drink energy drinks and Mountain Dew, also called slug juice, and enjoy large quantities of chocolate milk after dinner.

Rarely works out, usually only three weeks before Christmas or Easter break to impress the high school girls back home, but when they do they make sure to work their whole body, by whole body I mean biceps and abs (the biceps of the stomach). Prior to this three week period a slug will purchase copious amounts of work-out supplements, or "sups" as they like to call them, to aid in their feeble attempts at acquiring the body of a Greek god.
Dammit there's no chocolate milk left in the mess hall, all the slugs drank it.

The weight room sucked tonight because all the slugs were in there getting their annual work out in before spring break.

I've been doing work and practicing all day and you've been in here sluggin' it up like a piece of shit.
