You should get a little distance (from this).
Good advice whenever things begin to heat up, especially if you’re the one who’s hot under the collar!
So take a few steps backward. That’s it. I’ll bet you can see the big picture now, right? It all becomes clearer.
That’s what prendre du recul means. Literally: to take some backup. If you look carefully at recul (well, it’s not very hard to spot!) you’ll see cul, a not-quite-polite-but-not-too-rude-either word for backside (referring to human anatomy, of course).
So reculer means to back up, or to move towards your cul. Note that you don’t pronounce the final l of cul, but you do in recul. Think of the l as a little wall to keep you from backing right over the cliff.
