Answer 1

While this may make a bit more sense with context, the speaker is saying that he is a heavy-set man. The first sentence means that if he were to have an "outie" belly button, it would be more appropriate for his figure, which is round, and sturdy ("keg-like"). 
He then discusses how he has chipped away at his father's genes since he realized that he was destined to be significantly overweight.
