scrub chub 

When you can see a man's jewels through his scrubs due to his enourmous cock and balls or when a man in scrubs is suddenly overwhelmed with an erection which can be seen through his scrubs.

"Did you see Bob's scrub chub today, Sue?"

"Yes, and he is quite endowed! Is he single, Jan?"

chub in the scrub 

In a hospital setting, it is when a male wearing scrubs is suddenly overwhelmed with an erection, largely due to a attractive female employee displaying her attributes on purpose or otherwise.

"Did you see that chick on 4 west?"

"Yeah! She's smokin', I got a chub in the scrub when she dropped her pen and bent over to pick it up!"
