This term refers to those unfortunate souls who usually only step on the ice with 14 seconds to go when your team was initially down 4-2 but gave up an empty netter to make it 5-2. The coach finally calls the "dusters" number and does so in a way that the duster feels like he is finally getting an opportunity to showcase the talent he doesn't really possess. Why the term duster? Cause this plug has been sitting on the bench the entire game.............Collecting dust. Always the worst player on team.

A person who is absolutely garbage at a sport, game or anything really. This person is considered a "duster"
The term derives from this "duster" getting completely obliterated in anything he/she does and collects dust.
Example: A person who gets left in the dust.

Someone can be considered a "dust" if they failed an exam or if your just a "dust" and anything; can be sports, school, video games, etc..

someone who is horrible at something, most likely a sport

A duster is a moustache. There are many types of dusters. They can be handsome, tight, well groomed, mean, greasy, tough or pretty much just what you feel about it.

The stuff that is used normally for getting the dust out of the keyboard, but when it is inhaled you can get very high from it. You normally take 3 power hits.1st hit-sensation of dizzy or numbness, 2nd everything is slow and people talk like wooaahh and the 3rd hit you see a bunch of little squares. it is recommended to not do any more than 3 hits.

I can honestly say...it's not a trenchcoat.

a.k.a mustache, a solid mustache with good length and volume, named for its ability to collect dust.
