That Was So Funny I Forgot to Laugh!
A phrase used to mock someone when they say a joke or something they think is absolutely hilarious, but everyone else thinks it's retarded. Sarcasm in its most extreme form.
Chad:  "Okay, okay.  A Care Bear and a ninja got in a fight.  Who one?"
Me:  "The ninja."
Chad:  "No.  The Care Bear.  You see, it had just eaten an eighteen inch burrito, and it farted.  The stank smell killed the ninja!  HA HA HA HA HA HA HAAA!!!"  *more annoying laughter continues*
Me:  "Wow Chad!  That was so funny I forgot to laugh!"
