Zeno's leftovers
noun phrase
The paradox that occurs when no one in a group wants to finish a shared food item and keeps taking half of what remains.
After a pleasant dinner, Scot and a few friends were wrapping up with some banana bread for dessert. When he noticed that people were taking smaller and smaller pieces, he realized they were headed straight for Zeno’s leftovers unless someone took the hit and just finished it off.
