Pre-landfill noun: all that crap at WalMart and the dollar stores. Usually but not exclusively constructed of plastic. The stuff you usually receive from co-workers and in-laws that don't really like you.
Use in a sentence:
Ugh, my mother-in-law's taste runs to the likes of pre-landfill.
(This is the time of year that you see massive amounts of pre-landfill. Christmas gifts purchased and regifted but still not tossed, Mardi Gras trinkets, sappy and cheap Valentine's Day gifts such as those stupid stuffed bears, etc. Next round of pre-landfill - Easter crap. )
