look up any word, like plopping:
To freeze. Often used as a synonym for thaw or defreeze, although this is hideously incorrect. It actually means the opposite, when taken literally. Don't argue it. You are wrong.
Pete "The pizza was frozen so I let it unthaw for half an hour."
Willy "Get the fuck out of here you hick. And for the record, it's 'thaw'."
