Not everything can be found in a "google" search, "Soccer kids mum" is lingo mainly used by Americans and for Americans, when someone says "soccer kids mum" i often refer to the "Movies" and tv shows alike. i picture a mother with her son or daughter, taking their child to a sports event with half the neighborhood kids pinching a lift with her. She then begins to socialize with the other mums on the side lines,she's recently divorced, and so is little Timmys father, so she talks to him every other practice day, and because practice is on fridays, "Soccer mum" and little timmys father take all the kids for pizza afterwards
