Get an airhorn and when they get super loud give it a few blasts and scream "gooooooooaaaal!" At the top of your lungs. Max volume. Do it each time they get loud. If they ask you what you're doing say you're watching Euro footie.
Genuinely I think the right answer is to have something really loud and off-putting for them (especially her) and an air horn perfectly fits the bill.
