The image of a whale being carried by a number of birds that appears when the Twitter website is overloaded or has failed. Failwhale appears to now have his/her own fanclub.

Word origin: from fail + whale (probably for rhyming purposes).
Sad that Twitter had failed just when he needed it most, he was somewhat consoled by the appearance of his beloved Failwhale.

Get the mug
Get a failwhale mug for your dog Trump.
A annoying blue whale that turns up on the homescreen when popular social networking site Twitter goes overcapacity.
It is depicted as being carried by a flock of blue birds (the Twitter "mascots") to show that the load taken by the microblogging site is to huge to be processed.

In my opinion, it's plain irritating.
If Twitter goes overcapacity again, Imma throw that damn #Failwhale into the oilspill

Get a failwhale mug for your fish José.
An ignorant obese person who does not know his/her place in life. It often shows by being the loudest, most obnoxious person in the room, as an attempt to make up for his/her obesity.
Guy 1: "Look at Tim over there, thinking he's the center of the freakin' universe!"
Guy 2: "Well he does have his own gravitation point"
Guy 1: "lol - He just wont recognise his place in life. He's such a failwhale"
Guy 2: "Amen"
