Uffff 

What little kids online type for attention, practically begging for an online date.
An irritating text sound most likely connected to little attention and lots of sexual desire.

Mostly used in games, but can also be found online on sites such as "tumblr".

Example: an abandoned japanease horror app game called "Murder Online", where the chat is anonymous and people should just play, but instead, kids sit around and only chat, pasting roleplaying names before saying something, and pretend random kids also chatting are their friends or boyfriends/girlfriends. They will sit around in the game doing nothing but chatting hiding outside the map from killers that actually play the game correctly, and paste a roleplaying name every time before they speak, and think this abandoned app game and the other kids on it are their life. It's really sadistic.

urfff 

its like burping but instead of a loud its silent and gaseous...usually accompanied by the smell of your last meal. A bad urfff can be directed towards someone so that they may smell it. Never urfff in a car with closed windows. Pretty much like farting through your mouth. Urfffs are better sociably because no one knows you did it.

I had a hot dog with soda and it made me urfff. I can taste it and smell it in my mouth.
