There's no doubt that Jenelle Evans had the most emotional story line during Teen Mom 2's shocking Season 4 finale on April 29. Basically, we spent the entire evening eating our emotions and gentling rocking back and forth as tears rolled down our faces.

Not only did this gal take a trip to the psych ward, she spent most of the episode under the influence of drugs while her son, Jace, innocently asked if he could visit her. Sob!

Jace currently lives with his grandmother, Barbara Evans (who's had custody of him since he was an infant), and fans were shocked when he called Babs "mama" during Teen Mom 2's epic season finale. Does this little dude think Barbara is his mom?!

As if! Turns out Jace calls Babs "mémé" — not to be confused with "mommy."

"He says 'mémé' it's French for grandmother," Jenelle explained on Twitter. "Our family tradition."

OMG, you guys! Jenelle is so sophisticated! Before long she'll be enrolling Jace in a bilingual school, chomping on organic homegrown kale, and becoming best friends with GOOP (aka Gwyneth Paltrow).

Also, mémé might just be the cutest nickname we've ever heard.
