look up any word, like dirty sanchez:
 
1.
A word that can be used to conclude any sentence in any given situation regardless of circumstances.

It is also fairly arousing.
Sam: "turns out that squirrel kept jogging all day!"

*laughter*

Tom: "haha sigh.........eucalyptus"

2.
1- Word used to deconcentrate and adversary/ies while playing cards. Works best when you hit the table on which you are playing on while shouting it out without the slightest idea of what you are doing and ignoring the fact you ever said anything.

2- May also be use at the last word of a card game symbolizing the euphory of winning. This might also cause a side effect which is the unceasing laughter of you and your adversary/ies.
1-*Hits the table*
Player 1: Eucalyptus!
Player 2: ..... wait what?
Player 1: What?

2-*Hits the table*
Player 1: Eucalyptus!
Player 2: ..... wait what?
Player 1: I don't know... but I win.
Both: *Unceasing laughter for an infinitly stupied reason*
