Formerly an exclamation from being struck in the stomach by a fist and having your breath forcibly ejected from your lungs, it has now come to be a random utterance for those who don't know how to begin or continue a conversation. Or say anything useful or informative, really.

"Oof" is a common death sound, reffering to the popular online MMO "Roblox". It is used in many memes and quite frankly, used when you dont know what to say to something unexpected or cringy.
Pablo: Hey, have you noticed that whenever a conductor ends the song, they t-pose for half a second?
John: Oof.
