Meeting Girlfriends Parents/Playing Poker Summer Job

[bad_carma]

I"m going to meet girlfriends parents for the first time this weekend and the first thing that always comes up is "What are you doing for a Job this summer"? I don't have a job and am just playing poker...which i'll make more money than any summer job would provide. Of coarse anyone that doesn't play poker looks at this as simply gambling and is not a legitamate job. I don't want to say i just play poker and come off as a freeloader or lazy. What should i say?
