Short cut definition for a one-on-one meeting between an employee and their boss. Commonly used in the subject line of an email or meeting request. Not intended as a formal meeting to review one's performance evaluation, this meeting is often only 30 minutes and is conducted weekly or every other week.

"1 of 1" means one part of one whole, which originates from the spiritual concept of non-duality or oneness.

"I am 1 of 1." - person A
"What I am?" - person B
"You are also 1 of 1. There is only one source; you are just one expression of it." - person A
