More Craigslist Fetish Fun

I'm a chubby guy in town this Friday to Sunday (3/3-3/5) looking for chub chasers or chub enthusiasts to hang out with and keep me company in or out of my hotel room. [craigslist]

I do not claim to be up with fetish lingo these days, but could someone please explain to me the technical difference between a chub chaser and chub enthusiast. The only thing that I can think of is that chub chasers like engaging in sexual relations with people of substantial girth while chub enthusiasts simply work for the advancement of chubby people. Like the NAACP, except the CP stands for chubby people.
