No, this time she wasn't #lawrencing anyone either!
While talking to E!'s Giuliana Rancic about her award show outfit, J-Law mentioned her "armpit vagina" and even made Giuliana paranoid about hers... and it was hilarious.
Just in case you aren't sure what exactly an "armpit vagina" is...it's apparently the thin rolls of skin that bulge into the upper armpit from a too-tight dress. As much as we hoped J-Law just made up the word, it actually has been used before. Read all about it and see an epic pic of one here!
If you want to watch J-Law's funny moment with Giuliana on the SAG Awards, check it out in the Vine clip below.
We honestly can't wait to see what awesome trend or word Jennifer accidentally comes up with next!
