Translation studies Puns

I'm brazilian and in Brazilian portuguese is very common to ask something from someone (mainly food) by saying "me dá um pouco/pouquinho disso?" (which means "would you give me a little of that?")

Everytime I do that to my dad, he uses two fingers to take the tiniest possible slice of the thing and give to me in my hand or plate with the most serious face possible. If I complain he procceeds to say something like "you asked a little, didn't you?". My mom everytime laughs at that.
