"Squash up" is a phrasal verb that means to make something fit tightly or closely together by pressing or squeezing it. For example, if you have a lot of clothes in your suitcase, you might need to squash them up to make them all fit. Or, if you're sitting in a crowded car or bus, you might need to squash up against the person next to you to make more room for others. Essentially, it means to move things closer or compress them to fit in a tighter space.
