The ultimate in uptalk...
"I know, right?"
Seemingly ubiquitous and horribly conspicuous among people under thirty, its putative purpose is to show affirmation and agreement with an observation or statement made by another person. Yet at the same time, it is also a request that the other person validate said affirmation and agreement.
Not only does it evince an inability to make an assertion of one's own, it even shows an alarming level of uncertainty in simply being able to wholly agree with what someone else says.
Forget leaders, this generation struggles even to be followers!
