A person who pushes a door instead of pulling it (and vice versa).
(Note, the word can be changed to "ignominiting" to describe the action)
a semantic widening, almost, of the word ignominious
in the fact that it means something embarrassing, and the action is embarrassing for most people.
"You ignominite!", "You total ignominite!", "Oh, look, he/she's ignominiting!" etc.
