Someone who has a lot of the same interests and similar personality type. If you two were to bang it would be a cosmic event. You and your cosmic twin would be a great couple if you ever got together even though this would probably happen when you two are in your late 60s-early 70s

Get the cosmic twin mug.A person who was born on the same day of the year as you. A true cosmic twin was born on the same day and same year as you (aka a Sense8), but colloquially any year is permissible.
Of the past 5 dates I’ve been on, two of them have been cosmic twins. I guess that means astrology is wrong, since opposites attract.
