A person who is fat and lardy. An insult, sort of. Sometiimes a term of endearment.
Person 1: You're such a fatlard....!
Person 2: *runs away crying*
A person who is overwhelmingly immense, whose shadow can create a "lipid eclipse", who decides to take up all four corners when told to hide in a corner, and who lacks self esteem.
Brian D. tends to be a fatlard.
