An allotment of timely interaction one assigns to a group or a member of a group. A specific amount that serves as means of maximum exposure to an individual or a group sharing similar interests. When one reaches maximum point, one 'calls quota' before pleasant interactions evolve into irksome experiences.
"I have done lunch with you twice this week. I call quota on you before I get bored with you. See you next week."
Note: This is an example of a thought process. It is NOT advisable to speak of quotas aloud. If quotas are informed to public, there may be a risk of not having any individuals or groups to call quota on.
