Molly's Lexicon, 27 months

to bin: to insert oneself into a clear, plastic bin for fun.

She stood inside the bin (it's about 18" high) and said, "Mummy! Look at me, I'm bin-ning!"

She needed a word to describe what she was doing -- standing in the bin. Binning. I've never known it to be used to describe a game. I like it.
