What is In Like?
1.
the stage of infatuation where one is enchanted by another but not yet "in love"
She is so amazing - I am completely in like with her!
2.
Analogous phrase to "in love", to describe one's feelings for a person that one is interested in romantically but not currently in love with. As one can love another as a friend but not be *in* love, so can one like another as a friend but not be *in* like.
I think I'm in like with that girl we met last week.
