Retardical means something that is soo retarded! It is something or an act of some kind that is extremely stupid, retarded, idiototic, ridciulous, dumb, etc.
A play on the phrase rhetorical question, a retardical question is a question so stupid, it leaves the people being asked speechless, and unable to answer with even a sarcastic response. A retardical question has such stupefying power,it can leave an entire room in a confused daze, and, in written form, can kill as many brain cells as aerosol or a Miley Cyrus song.
Dude 1: What did you put in answer for number 9?
Dude 2: You mean "name something flat? I put pancakes, tortillas, Earth....
Dude 1: Wait what?! Earth?
Dude 2: Yeah it's flat right? That's what people say.
Dude 1 is so stunned by this retardical question he is unable to speak, or move, and has to be taken to the school nurse.
A door wall is a sliding-glass door or patio door. The term is yet another example of banal Michigan vernacular, where in the residents latch on to company names, trademark names, marketing terms and product names from local companies. The terms become embedded in the local vocabulary and eventually become accepted as actual valid words and phrases. In this case the term comes from Wallside Windows in Taylor, MI (a large window manufacturer), where 'door wall' is their created word for sliding-glass door.
"Bob! John's gonna bring over them doorwalls from Wallsides on Tuesdee afternoon 'round two-thirty. Get 'er done!"
