Saying that you would go out of your way to do something for someone. If someone is struggling or you care deeply about someone, this is what to say.
P1: Hey...my mother hasnt been doing so well
P2: Tell me what she needs, I'll reach over the toaster for her.

P1: What do you promise me?
P2: I will always be reaching over the toaster for you, even if you make me mad.
--------
P1: Why'd you two break up?
P2: I was sick of reaching over the toaster for her. All she did was keep begging for more. At that point, it wasn't reaching over the toaster, it was prison.
