Translation of fuzz in Spanish

I have started learning only one month ago, that was during the summer holidays, I want to go to Canada for three weeks and then participate in a course. I hope that I will improve it more or less.
Usually we write these messages twice a week. We also have a fanpage in Spanish where we need to write short messages. It is actually pretty boring but people respond to it. Don't ask me why they are doing it.
I can already speak a little English but not too well. So I'm more cautious about making mistakes. I want to improve my English, because it is also good for your confidence and communication skills.
