Any disc recieved from America Online that contains its product. Since using the programs represents a net inefficiency for your time, it is better to use them as coasters that you can set your drinks on, lest you damage a wood or other valuable surface.

I got so many AOL 9.0 coasters last month, I glued them to my ceiling and now it's shiny, disco-style.

Anything put under a cold drink to avoid rings of mist on the table.

I'll have a scotch on the rocks with a twist, and a coaster.

Coaster 

A girl that won't let you have sex with her (won't let you get the wood wet).

1) I'm not paying for your meal tonight because you're a fucking coaster.

2) E: I heard Vincy fucked Amanda after the party the other night.
J: No fucking way. That girl is a coaster.

Coaster 

a person who is paid very well at a job where they are not stressed and do not need to work hard or be ambitious at all. This person tries to fly under the radar and does only the minimum amount of work needed in order to greatly satisfy their bosses, and indeed the work is very minimal.

Kevin is just coasting at work. All he does is do a little work, show up to meetings, and then go home. What a coaster

Coaster 

A poser who rides his fixed gear on the freewheel and coasts rather than riding the fixed gear. Does it for the trendiness of the fixed gear rather than the function and purpose of the fixed gear.

"That guy wasn't pedaling when he went down the hill on his fixed gear, he is such a coaster."
