I have a lot of stuff in my room.

My nose is stuffed up.

He always handles rough stuff with care.

This store sells a lot of hot stuff.

I often talk about random stuff with my friends.

Despite the myriad of obstacles we had to overcome, we managed to engage in such fun stuff, it makes all the hardship seem inconsequential.

He stuffed down his lunch quickly.

I don't like when people make stuff up just to get attention.
