look up any word, like ratchet:
Someone who makes statuses in order to receive as many 'likes' as possible.
A LikeBooker would make a status requesting 'likes':

'Like this status if i have ever made you laugh'

or quoting lyrics from songs that people will know:

'Just a small town girl, livin' in a lonely world'
