Sure. In my mind, hosting is either for larger get-together that takes organizing and preparation or if someone is traveling to the area to stay with you for a few days.

Hosting generally carries the weight of planning, organization and preparation that probably doesn’t go into just having someone over to hang out.

Been using that forever, even in the internet. Ever heard of LAN hosting?

I don't hear it often, but being a host to people in your house is a normal thing.
