Keep up the fuss. What does the expression mean?

[Mohammad64]

It is a sentence in one of the Kitosdad's stories( Santa and the reindeer)

But that was really only the tip of the iceberg to his problems, because now those pesky reindeer were kicking up a fuss.

What does "kicking up a fuss" mean?

Thank you Our Tort System. I looked up "kicking up a fuss" in the dictionary (The free dictionary). However, I did not find anything. It was a search problem. I should have deleted "ing" in the end of "kicking".

Yes, always do searches for idioms with the infinitives of the verbs that comprise the idioms, because dictionaries list idioms that way, with infinitives.
Also, use Google to search for idioms that you do not recognize. Most of the time Google will bring up a lot of links to the sites/dictionaries where those idioms are defined.
