Heimbag

Referring to an individual who is reluctant to share while having an abundance of the resource;

Or,

An individual who has been invited to partake, but at their turn they take/do too much. This may seem like they are being greedy, but they don’t often realize the negative effects they have caused the group by hogging or consuming all the resources.

To prevent said heimbagging to occur, gently remind the individual that they need to continue the rotation and pass it on, or simply stop inviting them to partake in group activities - as for they consume more appropriately in no larger than a 2 or 3 person group setting.
