I just learned about this a few weeks ago:
"Twainbow is a portmanteau of 'twain' (meaning 'two') and 'rainbow.' Individuals with Autism Spectrum Disorder (ASD) who are also lesbian, gay, bisexual, or transgender live with two rainbows in their lives: what we like to call the double-rainbow" --Twainbow (
https://twainbow.org/ ).
I like the idea.
Rainbows are beautiful. Calling aspie+LBGTQ sort of puts a positive spin on our status. Good stuff.
