term used when in need of a wake up call; slang term used instead of the traditional wake up call; can you give me a waker upper in the morning; when someone needs a favour; needs that important call; whereas they're usually sleeping, and don't want to miss school, work, meeting etc..
person 1: "I have to get up early tomorrow, can you give me a waker upper call"!
person 2: "oh for sure; would you like that in the form of a call or text"?
