Do a search here on the DIS and you will find lots of threads about them.
Basically it's a national cheerleading/football championships held every year the first full week of Dec. The can be an absolute nightmare. I've been there twice during that time. The first time I was there they were at the All Stars and PORS, with the overflow going to POFQ. We were at POFQ and swore we'd never go back during that week. We didn't notice the football players, but the cheerleaders were totally out of control and their parents and so called chaperones were acting like a bunch of drunk sailors on leave. By the end of the week the employees were calling in and we saw a couple in tears. They made the Brazillian tour groups look well behaved. This past Dec due to scheduling problems at work I had to go back that same week again. I did a split stay at CSR and YC and never even noticed they were there. You probably won't even notice them in the parks, but if you're at the same resort they are, it can be a toss up. Some people say they are loud, but not a problem. Others have nightmare stories about them (fighting in the food court, throwing food and cutlery everywhere in the food court, taking over the pools and hot tubs, running up and down the halls all night banging on doors, giving CMs a really hard time, knocking little kids down, forcing themselves in front of everybody to get on the buses, practicing cheers in the early morning hours and late at night, etc). What's bad is the Disney CMs are totally overwhelmed by them and when you complain the general response is "We know, but what can we do?".
I know when we complained about them at POFQ, the CM's only response was "We know they're out of control and will see what we can do, but don't expect much. There's just too many of them. There's about 40 complaints ahead of yours". When I suggested they talk to the parents and chaperones, she rolled her eyes and said the biggest complaints were about the parents and chaperones.
