10 topics I've discussed off the top of my head:
- school (obviously)
- sports (especially American and "the rest of the world" football)
- video games (especially FIFA 14 which is big at my school)
- memes and whatever funny, ridiculous **** that comes to our deranged minds
- healthcare, socioeconomic and race politics
- anime/manga
- women (!)
- philosophy and the meaning of life
- music (I play drums in a band, too)
- LIFTING (powerlifting, bodybuilding, strongman, Olympic lifting, you name it)
There's more that I can come up with because I don't necessarily plan what I'm going to say. I just say it and let the pieces fall where they may.
