if you don't know here is the urban dictionary definition:
"A person who is "on the hook" will be overly infatuated with another person. The person who is the desired generally takes little notice (and often complete advantage) of the person who is on the hook.
Often times the person who is on the hook is a back-up."
if you watched that HIMYM episode where ted is on carrie underwoods hook then you know exactly what it is.
