When someone orders food that's
shareable but meant for only
that one person, moochers who want some part/portion for themselves call "
secondary beneficiary" like one would call "shotgun" to claim a seat in a vehicle, when preparing for a ride. Roommates, friends, and family are notorious for such moochery.
Christine ordered a pizza for herself and tried to keep quiet about it. As soon as it arrived at her house, her
little brother called
secondary beneficiary.
