The above commercial for Bring It On: Fight to the Finish uses the word "sweat" as synonym for worry. "You sweat me because I am a way better cheerleader than you!"
When I was in college it meant you had a crush on someone. "She totally sweats me, dawg," or "I sweat you!" It sounds sticky and gross but is a compliment. I never heard any of my friends say it, but allegedly ultra cool, partyin' hard and clubbin' crowd used it on Facebook.
Urban Dictionary corroborates both uses.
Unfortunately, Old People, this is the kind of word that may make you look older when you use it, so I advise using "sweat" as its original meaning.
