Go dance: salsa, tango, rock'n'roll, whatever you like. If you're young, salsa or street dance may be more interesting. Dancing is connecting to people without the need to talk much.

If you really don't like to dance, try theatersport or "impro". It will help free your mind.

Big bonus: you will meet many people that are not in tech. And afterwards you go have a drink in a local bar, great moments to talk to other people.
