rainbow up
the politically motivated practice of diversifying the gender, racial and ethnic makeup of an organization or institution.
I just looked at our quarterly employee demographics. We really need to rainbow up by the end of the year.
Throwing up rainbows
Saying encouraging or comforting things to someone who is whining/crying/feeling sorry for themselves when all you really want to say is suck it up.
"Vanessa's useless, cheating boyfriend sent her a break up text yesterday, so I got stuck listening to her whine & cry about how she'll never find a good guy. I spent the night throwing up rainbows to make her feel better."
Rainbow light up party dildo
Could either mean that someone is a party animal but it is also exactly what it sounds like
"They are such a rainbow light up party dildo" or "they used a rainbow light up party dildo"
