Loser. 45 is a Loser. 45 is the biggest loser in the history of the United States. Many people used the term 45 to identify the loser who occupied the White House from 2017-2021 because the very sound of the name of the loser in our mouths made us gag and throw up. 45 has become synonymous with being a sore loser, one who makes up lies rather than accept the rank of the world's greatest loser.

45 is the biggest sore loser in history.
