For example, if there was a sofa in the room, and there were 3 people sitting on it, and there was a little space between their seat. How do you ask them to "move" or to "come close" to each other so that I can fit in, and have a seat with them?
Note: It's that one word that I'm looking for here that I used to know that you can use in this particular situation, but unfortunately, I'm non-native English speaker, that's why sometimes, I forget some words; It is used when you want to ask your seatmate to move to that empty space, or something like that.
Thanks for the answer.
