IHTLW 

Abbreviation for "I'm Having The Last Word" - a competitive game played by British children in c.1968, usually played in a shared bedroom shortly after bedtime.

Child1: (checking to see if sibling is awake or not) "I'm Having The Last Word"
Child2: "no you're not..."
5 minutes later...
Child2: "I am".
Child1: "No you're not, I am".
some time later...
Child2 calls name of Child1.
Child1: "what?"
Child2: "I'm Having The Last Word".
... continues until only one child remains awake and whispers, "I WIN!".

The object of the game is to "have the final say" before falling asleep. The Winner is often disputed the following day as nobody else was awake to verify his or her claim.

In brief: A game as silly (empty) as playing Tic Tac Toe (UK: Noughts and Crosses).
Some say the game was a method introduced by parents to get their offspring to go to sleep but this claim itself is also disputed; My younger brother and me invented it and IHTLW :P so there! Word.
