look up any word, like cunt:
When just after you gave a speech in public, you can't remember how you did or exactly what you said or how long you were talking.
"Dude, i have post-speech amnesia. Can you like record my speech for me so I can watch it afterwards and see how good I was?"

"Sure dude, I hate having post-speech amnesia. That ish sucks."
