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.

Get the Twinkie twinsmug. The coolest fucking buildings in the world which were created by Minoru Yamasaki who also made the BOK tower in down town Tulsa. (And some other buildings such as the ranier tower) unfortunately, these badass buildings were blown up by some assholes on 9/11.
The twin towers are my favorite buildings! They were so cool and nice looking. Too bad they got blown up.
