Yobnoxious
An obnoxious yobbo. Loud and stumbling. impolite. maybe a bevan. sometimes a yuppie becomes yobnoxious after a few Bundys, and it is a whole new side of a person you have never seen.... and maybe never want to see again. Yobnoxious people are rarely violent. Just loud!
When she drinks too much she is just SOOO yobnoxious!
