Hulk bulking is the art of bulk eating whilst going to the gym. Testosterone is also used as a boost by meat heads at the gym to get maximum gains. People who hulk bulk walk around with size XS T-shirts on to make themselves look even bigger whilst bulking.
"Hey sam, I hear you were hulk bulking the past few months! How's it going?"
