LAK or L.A.K. is an abbreviation for Larry Ass Kickers. Larry Ass Kickers are any tasks that become so difficult as to cause an individual to freeze up, stammer, or skip like a record player. LAKs can also cause paranoia, anger, and frustration. While the origin of LAKs is not exactly known, some psychologists believe that they are triggered by "muffin tops" or "moobs".
Originated from Winchester College. A notional corruption of the verb to like, meaning to not like. It can also be used in conjunction with 'don't' thereby reversing the meaning to I like.
