Derived from the Spanish chingar, meaning to fuck or to fuck up. It was in common usage in 1960s Southern California to mean "mess up." Past tense and past perfect is chungered. Almost always used in the past tense, as in examples, but can be used in present or future.
I hit a tree and chungered my fender.
Yeah, I fell off my bicycle and chungered my knee bad.
Oh wow, man. That tire is totally chungered.
If you go over that dirt road, you're going to chunger your oil pan.
Early 1960s teen slang, meaning sweaty and smelly. Based on the yeasty smell of sweat and related to a "batch" of rising dough. Heard in Southern California high schools. Girls, however, were never batchy.
Oh, man. I've got to get a shower. I have a date with Cindy, and she hates it when I'm all batchy.
