Fun drink to take “shots” of

I am a college student who doesn’t really drink due to medications I am on. All of my friends drink a pretty decent bit, and I often feel a little awkward in social situations when a group of them get up and go to all take shots together. We are going on a trip soon, so there is going to be way more of this.

What would be a fun nonalcoholic drink for me to take “shots” of so I still feel included? I know I could realistically just do anything (even just water), but I’d like to make it a little fun for myself.
