A "unicorn moment" is when somebody gets off the subject of a conversation, or when one gets "side tracked" from a task without realizing it.
EG1: person "A & B" conversation.
A:"We went to this show and it was cool, the bands were great."

B:"Who was playing?"
A:"Some local bands"
B:"When is the package supposed to arrive in the mail?"
A:"that was a total unicorn moment"

EG2: Person "A" intended on mowing the yard. "A" starts mowing the yard then stops to water the flower garden and completely forgets to finish mowing the yard.

EG3: Person "A" goes online to check bank account and logs into a social network site and forgets to check bank account.

EG4: "I don't have ADD, hey look a unicorn!"
