How would I say "give me xyz" without sounding too rude (or formal)


Let's say I've just been food shopping with my girlfriend and I want to say
"give me the bag" so that I can carry it for her. Could I just use 「くれて」, or
would I use something else?




Since you are trying to take over a heavy bag from your wife, I'd think more
appropriate expressions are:

  * `バッグ` (bag): combined with a hand gesture, just saying "bag", maybe just `ん`, or even not saying anything at all, communicates the right message. I prefer this the best, because the terseness shows that you and she are on the same wave length that doesn't nee too many words, which is generally seen as a sign of a long intimate relationship. otherwise known as 阿吽(あうん)の呼吸
  * `持つよ` ([I will] carry [it]) `頂戴(ちょうだい)` (pass [it to me]): similar terse forms that just uses a verb and omits everything else. This works, too.
  * `下さい` (please give [it to me]): a slightly formal word like this, when combined with exaggerated intonation, can add playfulness. 

I don't think くれて in a grammatically correct Japanese in this context, though
there's くれてやって/くれてやんな, which is more blunt/aggressive form that translates to
something like "just give it up already"
