Brain Tattoo 

an image which is extremely fascinating or horrifying that you see or is envisioned from a verbal description which stays in your mind for a long time or permanently to be recalled later at an inoppurtune time.

Aagh! I just got a brain tattoo of that pot-bellied dude riding a bicycle in only a speedo, a bandana, socks and shoes. I did not need to see his vienna sausage and mini plums.

Tattooed on my brain

A memory that one has that one can never forget and every so often it comes around and you have to deal with it.

Man1:I saw my grandmas pie and I can't get it out of my mind it's tattooed on my brain.
Man2: It's your memory so don't give it to me.
Man1:I wish the brain had an erase botton.
