1. In response to someone who has said/pointed out something very obvious

2. In response to someone who has insulted you or has aggressively disagreed with you

3. In response to a boring, nerdy comment you don't understand or care about (i.e. a peice of trivia)

4. In response to a comment that seems hard to believe or a lie

The call of the common Surprised Owl of Internet Land. The Surprised Owl lives in a symbiotic relationship with another species, unlike many of it's real world counterparts. The Surprised Owl depends on the call of rarer Unflappable Owl and vice versa to provide mutual acknowlegdement of each others existance, thus reafirming the fact that they continue to exist, and thus perpetuating their existance. For if either owl fails to respond, the other will soon perish and upset the delicate balance that exists in Internet Cliche Kingdom.

The response is not due to inherent lameness but rather through necessity. Many believe in the exist of other owls, especially the Proper Owl, but scientists have continued to discount all evidence.
Suprised Owl: O rly!?
Unflappable Owl: Ya rly!
