I've been using an idiom ambiguously: "That's small dice."
Does this refer to unfavorable outcomes in games of chance? (equivalent to "chump change", like "those are small dice"?). See also "no dice", which has origins in craps.
Or rather, is the idiom a reference to diced food? (equivalent to "overly scrupulous"?)
Example usage.
- 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
