OOF is a sound that plays when a Roblox player dies. However, Roblox removed the sound effect at the end of 2020.

Oof is the Roblox death noise. It is another way to say "Aw, man" or expresses the noise made when you get hurt.

What my life is a big oof I got banned off roblox.
Me and little jimmy were playing roblox and the next morning I was banned. It was a big oof and I had suicidal thoughts for awhile. So I slept with Jimmy’s dad which I ended his dads life. Because we had gay anal sex for 10 hours straight and he didn’t say no homo. What a faggot.
