I've been using an idiom ambiguously: "That's small dice."
Or rather, is the idiom a reference to diced food? (equivalent to "overly scrupulous"?)
- Sorry if this seems like small dice, but I've double booked Wednesday evenings...
- Also one time she accidentally tripped me in capture the flag, but that's small dice compared...(weird expression... small dice, what does that even mean?)... [sic] to this one time, we were on a bus going to a music contest for my orchestra, and some of the other people in orchestra dared her to call me "sexy". http://armorgames.com/community/thread/8027776/the-rant-thread
