In case no one gets around to answering you: Our American style of football is played at grade school, high school, college and professional levels. At each level, teams from different regions or organizations are organized into leagues. Some games are played on the home fields of rival teams in the league, and some are played on your own home team's field.
At the high school and college levels, primarily, the first home game of each new football season is called "homecoming." Various activities, rallies, and parties are organized around the homecoming event. Most schools pick a homecoming "king and queen" every year -- typically the most popular and/or attractive young people in one of the upper classes. They "preside" over the big homecoming dance. Hope this helps.
Thanks
I think I read somewhere that Barbara Bush (W's daughter) was homecoming queen at her high school in her senior year.
