Shoehorning is a term used to describe the act of forcing something into a tight space or situation. It is often used in reference to fitting a large number of items into a small space, such as packing a suitcase or squeezing into a crowded room. In other contexts, it can also refer to the act of forcing an idea or opinion into a conversation or situation where it does not fit. In this case, the term 'putting in a tight spot' is being used to describe the act of shoehorning.
