Something that you don't want to throw out yet, but you know you'll throw out eventually - for example, unread mail, not-quite-empty food containers, etm. Alternative form of prototrash.
Warning: Today's protogarbage is next month's paleogarbage!
My friend Peter showed me his pics from a recent trip he took to Los Angeles with his girlfriend. Surprisingly, he looked gay in every picture. I never realized how photogaynic he is.
