dust cover

A condom, in Australia that is not used for a long time, kept mainly in a wallet by teenagers awaiting the right moment to be able to say "I have one!"

There is a direct link of "dust covers" to the event known as "schoolies" where a handful of finishing teenagers are "finished" by older men.

"Bring you dust cover Jeff!"
"It never leaves my side - I wear it on my belt!"

dustover 

The hangover-like effects which are experienced the night after heavily abusing Dust Off, a beloved brand of compressed canned air which is normally used to clean computer keyboards.

Steve did half a can of dust-off last night and now he has a pounding dustover.

dustovers 

That fucking irritating line of dirt that is always leftover when trying to sweep a dust pile into a dustpan. Dustovers cannot be killed, only made smaller and smaller until they are barely noticeable.

I had to get the floor spotless for dorm inspections; but ever time I tried to sweep up the mess there were dustovers.
