“Do you still want to get together?”
You made vague plans to meet an old friend of yours this weekend, but you haven't heard from her and want to check to make sure that she hasn't changed her plans. You ask this.
Do you still want to get together?
Although this is a very basic expression, it's worth pointing out that this is the most natural way of inviting people to do something together. For example:
Do you want to go out for a drink after this?
Do you want to come with us?
You can also ask "Would you like to ___?" which is just a little bit more formal.
This means to meet and have fun with someone.
This can be used by itself as an intransitive verb:
We should get together.
Or you can specify who you're getting together with:
I'm getting together with some friends of mine later tonight.
This phrase is a good casual way to express the idea of meeting with friends. The word "meet" can sound too formal.
