When someone is exhibiting a period of focus and contentment largely because they have had recent-enough sexual release / orgasm. It is the antithesis of the slang "down bad", and is not to be confused with the phrase "post-nut clarity" (which is more descriptive of the immediate onset of awareness and objective thinking upon finishing climaxing).
"Hey you tryna godancing with us tonight?"
"Nah man I've been up good since yesterday and I'ma keep working on my thesis til it wears off".
Usually refers to men. Especially men who don't pay much attention to their looks, in terms of grooming, hair and clothes.
However when they put some attention to it they look good.
Best example is Shaggy from Scooby-Doo. He always looks frumpy, stained, unshaven, slump, but you always
get the feeling that when he needs to escort Daphne Blake to her gf wedding Shaggy after a shave and a nice getup will look good.
Girl 1: Are you crazy you want me to go out with Jonah Hill, yuck Girl 2: Sweety, he cleans up good and will make you look great on that red carpet
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!"
