I work with some younger people and I hate it too.
But what really chaffs my hide is when the girls over-use "like" while they say everything in the form of a question! Aaaaarrrrrgh!
"Sooooo, we were, like, going to see a movie?" "And the guys were all like, nah that movie is lame?" "So we went and hung out at the mall? And like, all they did was text eachother?" "And like,like like like like,...........like?'
