I love you like a fat loves cake 

a very cute lyric in 50 Cent's song "21 Questions". Popular in the Chicago area to say to someone you adore.
"And we only humans girl we make mistakes, to make it up I do whatever it take
I love you like a fat kid love cake
You know my style I say anything to make you smile"

Girl: I love you!!
Boy: How much?!!
Girl: Like a fat kid loves cake!
