I know quite a few ESFP guys. One thing they have in common is that are all very much into playing sports - basketball, skiiing, surfing, and weightlifting in particular, and don't have an ounce of beer gut in spite of how much they party. They're also fun as sh-t and will be friends with anyone. I've found ESTPs can give or take sports depending on personal interests.
Some ESTPs can also do the ENTP thing of one upping you, they like to show they know more than you. ESFPs rarely do that.
