rainbow draw 

When a phlebotomist or a nurse can't read the doctors blood draw order, they proceed to fill a testtube of every color just to be safe.

"I can figure out if the Doctor is ordering a blood test or his lunch. I'm just going to do a rainbow draw."

Rainbow Robbery 

When you meet a girl at a casino, and you hit it off. Then you get drunk together and take her back to her place. Once back at her place, you get orally pleased and then you rob her of her casino winnings.

Hey man, I totally pulled a rainbow robbery last night with that girl from the black jack table!
