noun.
An imaginary substance often used by someone (“the ninja duster”) who wants to leave a party where a lot of alcohol is involved, but is too afraid of saying goodbye to anyone (“the ninja dustees”), because saying goodbye might lead to a ninja dustee grabbing the ninja duster by the scruff of the neck saying “You’re not going anywhere - at least finish just one more drink with me!” knowing full well that it’s never gonna end with just one more drink.

The term gets it’s origin from the actual powder or “dust” used by ancient ninjas to disappear from the site of their enemies.

The substance exists in varying degrees of quality. The degree of quality can be measured by the length of time that it takes the ninja dustees to come to the realisation that the ninja duster has, in fact, left the party without anyone else noticing.

The four most common degrees of quality are: (Starting with the least qualitative)

1. Worst Ninja Dust:
The ninja duster is caught in the act of leaving the party and thus prevented from leaving the party. The ninja dust having failed the ninja duster totaly;
Example:
Ninja Dustee: “Hey dude, where do you think you’re going!? The party’s only just starting now!! Whoo-hoo!”
Ninja Duster: “Uhm.. Ahem.. yeah, no I was just stepping out… for some fresh air.. whoo-hoo..”

2. Good Ninja Dust:
The ninja duster is already on their way home or is already at home when the ninja dustees discover that the ninja duster has left the party;
Example:
*Telephone rings*
Ninja Duster: “Hello”
Ninja Dustee: “Yo dude! Where the hell are you?! You disappeared like mist before the sun!? I didn’t see you leave?!?”
Ninja Duster: “Yeah. I left an hour ago.”

3. Great Ninja Dust:
The ninja dustees only realise that the ninja duster had in fact left an earlier party the next time they see him;
Example:
Ninja Dustee: “Hey dude what’s up? Hey, how great was last Friday’s party!? Wait a minute, now that I think about it – I never even saw you leaving!?”
Ninja Duster: “Yeah, I know..”

4. The Best Ninja Dust:
The ninja dustees never realise that ninja dust was ever used.
Example:
Ninja Dustees: “Hey dude what’s up?!”
Ninja Duster: “Not much.”
Ninja Duster 1: “Hey dude, this party sucks. Let’s throw some ninja dust and get on outta here before Bobs corners us again and starts telling us stories about how great it is to be gay..”
Ninja Duster 2: “Yeah, good idea..”

The shortened version of the term Ninja Dust i.e. “ninja” can also be used as a verb.
Example:
Ninja Dustee: “Whoa dude! Did you ninja me last night or what?!”
Ninja Duster: “Yeah, it was a great ninja.”

verb. ninja dusting. The act of letting go a silent, putrid fart that permeates the room, and in an unsuspecting fashion, the perpatrator uses his hands to waffte the stench towards the nearest person.
