Bane tells CIA that if CIA takes Bane's mask off, it would be extremely painful. CIA reassures Bane that Bane is a big guy, implying that CIA is trying to reassure Bane as to his ability to take the pain. Bane counters this and expresses his own vulnerability, while also rudely insulting CIA for CIA's attempt at reassuring Bane, when Bane tells CIA that Bane is simply a big guy for CIA, not a big guy in general, and thus Bane is still afraid of the extreme pain of taking off his mask.
