Forever and 3

When you love someone so much and want to express that timeless love by saying it would last forever, yet forever does not quite cut it. So you add an extra 3 days just to be sure.

Lisa: Awww (heart-eyes face) (kissy face) (blush face)... How much you love me?
JC: I love you forever...
Lisa: Forever and 3??
