Yohanism: What Does Quick Mean?

I was reading Tangled, (Thanks for recommending it Mary Ann. I like POVs from men. )

Yohan: Mommy, can I borrow your ipad. Very quick lang, quick

Me: talaga?

Yohan: yes

Believing her, I handed the ipad. The moment she got it. She said

Yohan: just 24 hours lang mommy..

Whattt???!!
Me: Yohan! 24 hours is one day!

So, I'm reading the book in this tiny iphone..hay..
