What to say when in a crowded place
It’s too crowded in here.
I feel like a sardine.
We’re packed in like sardines.
We’re crammed in like sardines.
We’re crammed solid.
This party is wall-to-wall people.
It’s absolutely jam-packed.
I’m getting claustrophobic.
I need some elbowroom.
There’s no room to breathe.
There’s not enough room to swing a cat. (folksy)
Would you like to go somewhere quieter?
Would you like to go somewhere less crowded?
