the opposite of (n)egative is commonly believed to be (a)ffirmative or (p)ositive. however if you believe this you are a dumbass because that would be a picture of an angel or some random miscellaneous camera-type object, not a thumbs-up. YOU ARE WRONG. (y)egative is the true solution.

"wtfbbq" "(y)egative" "examples must have at least 20 letters and 3 words" "damn that sucks"
