I really like DJ Cookie

Tbh I can imagine them having a bit of an oral fixation or something, just because of the little party popper they've got in their "mouth" at all times in their Megastar skin. I think they'd moreso be the type to (in?)frequently (could they suppress or ignore it?) and absent-mindedly chew on things, like pencils or pens, though. But those are just vibes... and a bit of projection from me.

Realistically speaking (puts my thinking cap on [🤔]), they'd probably hate it if another cookie was smoking specifically at one of their parties. Because like, it's basically guaranteed there's gonna be a lot of other cookies *and more importantly /children/* there breathing in the air around them, so it's gotta stay a good quality and that makes me think that might cause DJ to enforce a strict no-smoking rule at many of their shows.

If they see a cookie smoking anyway, they'd give them a warning first. Maybe the cookie didn't know and DJ doesn't care about what other adults decide to put in their bodies anyway (DJ understands many do it for stress-relief), but they do care if such a habit destructively affects other non-partaking people around. If the cookie smoking ignores the first warning and repeats this offense several times more, DJ will straight up kick them out and ban/blacklist them from future parties and shows. (Nobody's allowed to drag the party down, regardless of whether they do it out true maliciousness, ignorance, or laziness. [If you're slacking off or not moving in DJ's vicinity they'll just straight up kill you ❤️])
