It is a phrase usually used when one is agreeing with another’s observation/opinion on a matter. One could say, “I agree” in place of “I know, right?” However, to respond to someone else’s observation with “I agree” may come across as giving one’s opinion when it was not specifically requested. By adding the, “right?” to the end of the sentence, one is agreeing but also deferring to the initial observation.

“I know, right?” tends to be a phrase used in casual conversation. It holds a similar purpose as the use of the word “totally” in surfer speak and the usage of “word” as a statement of agreement in hip hop culture. It is slang, and it’s meant to be used in an informal manner. However, as is often the case with younger generations, the phrase is creeping over into more formal conversations. I think it is more easily co-opted than “totally” or “word” because on the surface it is harder to define it as slang than those other words.

It’s very hard to get away from these things–even though they drive us up a wall sometimes!

In my office I’m starting to hear the girls say “Yeah, right?” as often as “I know, right?”

Two that jump into my mind right off the bat (there’s an idiom that might annoy people who don’t use it) are these:

“At the end of the day…”

“In the final analysis…”

I believe the former is a metaphor about which most speakers don’t reflect very much. (I am at the end of my school day as I type this. This is the moment when the phrase resonates with me.)

The latter phrase seems to me to be an overstatement, since it’s usually uttered in the absence of any great in-depth analysis–certainly not after the ultimate analysis of an argument.

“I know, right?” This might be annoying, but it’s impossible for me to call it “wrong.”

Here’s the primary translation of “I know, right?”:

“I want to agree with what you’re saying, but I’m not confident enough to merely state this, because I don’t want to come across as arrogant or as trying to dominate your comment. So, I will include a token act of humility along with my acknowledgment by deferring back to you, the original speaker, for the last word.”

Yeah, I know, right? Gotta be in their twenties.

I don’t understand, exactly, how you can draw that conclusion. They might be in their mid-teens. They might be over thirty.

In any event, whether you love the phrase or not, I think Amanda has hit the nail on the head when she says it’s useful in response to a statement that’s “absurd but true.”

In certain groups of speakers and in certain conversational contexts it really is a perfect response. Not among all speakers and in all contexts, to be sure.

In my original post I was very careful not to deprecate or judge the use of this phrase. I find it curious, but hardly disturbing.

I’m grateful to Amanda, in particular, for posting such a thoughtful analysis of the phrase. It’s been in widespread use for some time, so the genii is out of the bottle. Now I want to understand exactly how it is used and what it means.
