Apparently I'm a shady person?!

The guy that I like ( and who I thought liked me back) called me a super shady person. We used to speak everyday and then next thing he just stopped replying. I've seen him twice since then though and I messaged him today saying " hey stranger!" And he messaged me back saying " hey super shady person 😜" I'm not sure whether to take it as a joke or not? I'm not sure what I've done for him to label me as shady. I asked why he says I'm super shady but I got no reply. What do I do? I really like him.
