The Alot is an imaginary creature used as a coping mechanism used by lovers of proper grammar. Instead of becoming angry at the incorrect use of 'a lot' found throughout the internet, the Alot allows the grammar-lover to imagine a sentence that actually makes grammatical sense.
The Alot looks like a cross between a bear, yak and a pug dog, and was created by the author of Hyperbole and a Half. Original description (with pictures) can be found there.
"I am sad, Alot." (I am sad a lot.)
"I care about this Alot." (I care about this a lot.)
