I Hate the Rich

I haven't been practicing drums much, but I've been meaning to learn I Hate the Rich by The Dils for a while now. It is deceptively easy...except there's this triplet tom thing. I can't figure out how the hell you get from "the groove" such as it is to the triplets. No video documentation that I can find to help. Will ask at lesson today...but stuff like this baffles me.
