Fuzz refers to a soft, fuzzy feeling or texture, often used to describe something that's been made from animal hair, like wool. Fuzzy things can also make a lot of noise when moved around.
When you're watching TV, you might hear the announcer say "We've got some new footage of the protest, but it's all just fuzz - we can't really see what's happening." That means they're having trouble picking up any clear images. This is because TV signals often get a bit distorted and turn into fuzzy static when there are problems with reception.
A frizzy mass of hair or fibre.
To make fuzzy.
