oh

Something someone says when they aren't witty or funny, but they like to think they are. It can express all sorts of emotions, anger, annoyance, betrayal, denial, acceptance, but mostly stupidity. It is said most often after someone tells a really pointless story and you want to make them feel embarrassed or something. If someone is threatening you, and you don't want to seem like it bothers you, say O, and then look at your friend right after. You feel cool, but you look like a dumbass normally said in a very short way, instead of "ohhhh" it's "o"
