A word/phrase used to annoy the hell out of adults and some teens. the word was created by a group of teen-age boys. it wasn't intended to become popular, but became an overnight sensation. most guys, and some girls make the noise. generally, people who dont like the noise cannot make it. the word is pronounced Baaeeeh in a high pitched voice. other words were created off of this word such as, berg (burg), duyaye (die-i), dagh (daggg), oooog (pronounced as sounds), and annoy people just as much as bagh. The phrase is all over the net and is popular on Youtube. the teens who make the noise are usually the popular kids. unpopular kids usually cant make the noise, or just dont want to embarrass themselves. The noise has been banned either from certain classrooms, or schools in general. to some people the noise is annoying and headache worthy, but in my opinion the noise is humorous and entertaining. to sum it all up: Bagh is a funny way to see teen boys get in trouble.
