"Hell" can be used as an interjection to express annoyance, frustration or anger, it usually comes at the start of a sentence. In American English, it can also be used neutrally to add emphasis to a sentence. Ex: Hell, going bowling with you guys was the most fun I've ever had. (American emphasis use) Ex: Hell, my boss is going to be angry with me for missing my deadline.
