brain spam is when there's tons of unsolicited thoughts, images, and sounds incoming amongst what's actually pertinent and relevant information.

When a person repeats the same stupid troll tactics so much it hurts your head to read it.
Spammer:Boy I am the best troll on here. You must be so butt hurt.
Victim : You have said that so many times it is turning into brainspam.
