An automatic reflex of the human brain that makes you forget everything you have previously known the moment you actually need it.

Some things that trigger delete mode are:

a) being on stage
b) being in the presence of a very attractive person
c) taking a very important test
"I can't believe I forgot the lyrics to my song at the talent show! I swear I knew every single word of it, but when I was supposed to actually sing it my brain went on delete mode!"
