It reminds me of a game called "Nobody is perfect" where there are cards with names and words that usually only few people know (don't worry, nobody is perfect). Goal is to write convincing explanations for them.
Each turn, one player draws a card, reads out the word, name or situation listed and writes down the correct answer shown on the backside. All others think up an explanation and write this on their piece of paper instead. At the end of each turn, the sheets are collected, shuffled, read out by the active player and the players have to vote for the answer that they think is most likely to be correct. Points are awarded if they chose the correct answer and additional points for everyone they fooled with their own creation.
(And now the question is whether the described game actually exists.)
There used to be a program on the Belgian national French-speaking radio called "Le Jeu des dictionnaires". The rules were similar but the radio hosts never played seriously, and just made up absurd and hilarious definitions.
