The line comes from the 1971 film Willy Wonka and the Chocolate Factory, adapted from Roald Dahl's 1964 novel Charlie and the Chocolate Factory. In the scene, Wonka invites his guests to lick fruit-flavoured wallpaper and names the snozzberry as one of the flavours. The invented fruit and the perfectly circular explanation made the exchange easy to quote out of context. It later spread through movie clips, reaction posts and soundboards as shorthand for nonsense answers, strange flavours and confidently explaining something with no real information.
