To be pleased by something.

Traditionally the word for erection, "boners" has taken down the same path as the tits, developing a figurative meaning despite its more obvious origins.

"Boners" does not always connotate sexual interest.
"Wow guys I am all up in boners about this new movie coming out."

"Tom is boners about his new car."

"Danny popped like five boners over the idea of spending the winter in Hawaii."
