Someone who is one of more of the following:

fat, ridiculous, rude, big, toadish, grumpy, ill-mannered, rude, a stick in the mud, always in the way

Just picture a fat grumpy old woman with a huge rear end who is frowning awfully at you from across the room, while wearing a housedress as big as a house, with her hair going every which way, and either glasses or warts or too much makeup, or all three.
That blump sat there like a toad all day and watched us and wouldn't even get out of the way when we asked her nicely to move!
