POTUS means 'President Of The United States' and i always thought it's a racist insult

I was never interested in finding out what POTUS means i read it thought
When they want to use words like that, let them do it but yesterday i watched the movie Brake with Stephen Dorff
where he said Potus needs to be saved. First I was like but then, after i realized what POTUS means

Afterwards

Sorry GLP!
