(surprised to find that bag is really a verbe).
Don't remember having it ever seen used as such.
can I bag your groceries? or we could go out and bag some game?

It is a verb in Australian everyday usage. From Collins Compact Australian Dictionary:
"
bag vb 14. Austral slang to criticize"
To bag someone or "bag them out" is to tease or provoke them with insults, often in a jocular way amongst friends, but sometimes in what amounts to bullying. I suspect it probably comes from Cockney slang. It also occurs as a participle,
bagging/bagging out.
A similar trem, "sledging" is often used in cricket and other sports of disparaging or rude comments made to your opponents to put them off their game.
