Seems to me that if you were being asked about a business trip by someone then "Cleint" would best describe the gent your visiting.  If your being asked about a personal trip or vacation then "friend" would probably be a good response.  

Does this question come up when explaining your travel to family?  That may be a situation that you prepare for differently.

call me

CONNOISSEUR works for me..

Space Shuttle Commander, I have business cards made up and everything

I like to sniff girls buttholes, it produce such an pleasant aromatic smell. Sometimes I get light headed, but that's a small sacrifice I'm willing to take.

or Large, both will make me smile, and get you many thanks!

We are sort of sweet, ain't we?

I know it is silly but it is a bit too dehumanizing for me. Anything else is fine.

i think in this sense everyone is a gamer.  we are all playing the game. we might have different roles, but regardless of that fact, still participants in this game. providers are gamers, they play with hobbyists.  hobbyists are gamers that p4p with providers. in a sense we are all gamers. safe to call it a game than a hobby. i think its much more non chalant than a client, regular, friend or whatever.  try gaming buddy or league member or some shit like that. i hate that stereotypical reference of us as johns, hobbyists, mongers or the like. i am a gamer!

I prefer not to be talked about, period.  Why can't you say you have business and/or pleasure in the area and leave it at that?
