What does it mean when a guy has a secret business?

So I like this guy and has some shady friends but he claims not to be in a gang anymore. But when I msg him asking if I was texting his iPhone that he smashed yesterday and he said "No dats da business phone lol" so I asked him " oh… What business? I didn't know you were a business man haha" than he told me " it's a Super secret business lol". So do you think he's in a gang, possibly even selling drugs? Please help! I like this guy but I'm unsure if he's actually the guy I think he is. 10 points?

Duh. Drugs or stolen property

He sells drugs. His immature texting didn't give it away?
