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.

He stuffed down his lunch quickly.

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

He may come across as a stuffed shirt, but he's actually quite down-to-earth.

He spoke stuffily at the formal event.
