Hi everyone,

I'm translating a short story about 3 poor brothers. In this section, they are playing football with the stones of the fruit they have just eaten.

مصّوا كل النسغ المحیط بالبذور قبل أن یجمعها محمود، ویصفّها على الأرض ویبدأ ببذرة دراق یطیّرها عالیاً، ویشوطها برأسه كضربة كرة القدم الرأسیة، ویصدّها أخوه. محمود یشوط بذرة الدراق كمهاجمٍ عتید، وأخوه یصدّها كحارس المرمى البطل. كانا یشبهان فقراء البرازیل، یشبهان رونالدو، ورونالدینو.

I have found that عتيد can mean either "future/forthcoming" or "accustomed/familiar". I'm wondering if it's clear to anyone what the writer's intention is here. These are my current options:
- he's so skilled, he could become a football player in the future
- it seems he's very accustomed to playing football with fruit stones (nothing to do with his skill)
- it's clear that he plays football a lot (nothing to do with his skill)

Thanks in advance!
