45

A 45 pound (20kg) standard weight plate used on Olympic barbells. Often referred to simply as "1 plate" or "a plate".

I hit a new personal best on deadlift yesterday repping three 45's. That's 160kg, not counting the bar!

1. The number that is after 44 and before 46

2. A Colt 1911 .45ACP. Despite only holding 7 or 8 rds, the 45 is like twice as powerful as a 9mm, even if the bullet is slower. Usually a term only given to a colt because most other .45ACP guns look like 9mms at a glance

Dude: Im gonna put a 45 in that asshole if he dont watch

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.
