Did R-Jeezy Go From G to Gent?

I'm in the middle of making dessert for our family's celebration of Mother's Day, and I realized that my mom doesn't have any wax paper. RJ was talking about getting some orange juice, and he made it sound like he was going for a quick run to the store. I asked him if he could get some wax paper while he was at it, and he replies roughly "I'd like to take a shower first. I've got three layers of sweat on me."

"From what?" I asked?

"The first one is from the driving range..." 

I take this moment to try to interpret what other definitions of "driving range" there are. Because surely RJ didn't mean that he went golfing. Alas, I didn't know what esle driving range could mean. "As in golfing?"

"Yeah, I decided to try it out."

"Are you getting bourgie on me?"

"I've gone from G to gent. Ay, I'm out there wearing my black slim jeans and a V-neck." (As though this gives him more street cred.)

Apparently, it's a work thing.
