A sexual orientation in which you are only attracted to Jared Leto and/or Shannon Leto (of 30 Seconds To Mars). You may find that the other men you try to pursue just simply do not compare to the sexiness and sheer talent of the Leto brothers, so you give up on guys.
Becoming Letosexual may cause the delusion of actually thinking you and a Leto are meant to be together. But this thought is more comforting and less painful than actually being in a relationship with someone who will eventually break your heart in the end.
a old version of sexting back in the 1800s trough the 1960s before phones were around, some one would "letsex" if they were horny back in the day. this process was very slow considering it might take a week to get a reply.
