Term used in the Modeling Industry when a model goes out to meet with an agent/agency, manager/management company, designer, etc. It's basicallylike an audition.
I was so nervous on my very first go-see, but the woman at the agency was very nice.
A reference to a classic book published in 1937. In the book one of the main characters, "Lennie" murders a women by mistake because he had a mental disorder and she was trying to seduce him into doing sexual acts with her... its alot to explain.
tldr: She told Lennie to grab her hair, he grabbed too tight, she screamed to let go, he paniced and killed her. So Lennies best friend, (another main character) George took Lennie to go see the rabbits i a forest by a body of water so Lennie could be in a happy place before George shot him in the back of the head because he was worried Lennie would panic and kill another person and get in even more trouble.
To "Go See The Rabbits" yourself or to take someone else to "Go See The Rabbits" could be subtly refering to suicide, putting down a pet, or murder.
