Gretchen Wieners used it in Mean Girls to describe something that was cool or awesome..Gretchen said it was "like slang from England"

Make oneself or another highly sexually aroused, to the point of orgasm.
Probably an old-fashioned term that won't fit well with the modern use of the word. It's repeatedly used in the anonymously authored, Victorian era 'My Secret Life' (quoted below).
It seems almost interchangeable with actual orgasm. It's certainly more than just getting 'turned on', but it does seem to be distinct from 'coming' (or 'spending' in old-speak).
I do recall the word being used in an early 80s UK TV drama in reference to male ejaculation.

Something that just isn't going to happen

An exclamation of either anger, suprise, dismay, or joy.

A button on your remote that makes people in the house bring you sandwiches.
