If the room is so small that we all squash in there.
Can I say :
The room is squashy.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
If people knew you were referring to a room, you could say 'it's a [bit of a] squeeze', but squashy refers to consistency. A ball can be squashy, a sponge is squashy. You'd only get a squashy room in a fairy story, with a giant who might squash rooms.
