Famously quoted from the 1971 movie Willy Wonka & the Chocolate Factory a schnozberry (snozberry) literally refers to the particulates (berries) that come from a nose (schnoz) i.e. boogers, snot-rockets, nostral-turds, funky junk from the face-trunk, etc.
Stan: Did you see the size of that nose?
Lou: He couldn't pick those schnozberries with a backhoe!
In Roald Dahl's Charlie and the Chocolate Factory, Willie Wonka mentions licking snozberries. What most people don't know is that in one of Dahl's adult books, snozberry is a euphamism for penis. He was slipping dirty humor into a kid's book for his private amusement.
"...The snozberries taste like snozberries..." "What's a snozberry?" "I'm a trifle deaf in my left ear, next time speak up!"
