shen 

Short for "shenanigans".

When dining with a group of friends, it is perfectly acceptable to tamper with or "shen" their food, drink or personal property if they leave the table at any time

The only way to counter a shen is for a person to declar "No shens." or "No shenanigans." when leaving the table temporarily.

"Bob got up to go to the bathroom and we totally shenned him! We hid sugar packets in his coat pocket and mixed salt in with his Coke."
