J’ai la flemme • I can’t be bothered • /ʒe la flɛm/ #frenchwords

I looked it up and yes, this word came from the word for phlegm, or mucus, one of the four humors, which supposedly causes sluggishness if you have too much of it. That’s where we get the English word “phlegmatic.” (Other humor-related words include sanguine [blood], melancholy [black bile], and choleric [yellow bile], which also gives us the French expression en colère.)

So, next time I can’t be bothered to do something, I’m going to say “I have phlegm.”
