demom 

It's a jointing of the word demom and mom, and it's when you have a mom, who is so bad, that she's a demom sent to torment you from hell.

Girl 1: Ugh, my mom is literally the worst! She's always on my case!
Girl 2: So she's a literal demom?
Girl 1: Uh-huh.

Demomify 

When you have a car that a mom would drive, a pussy car most would call it, if you get made fun of the the car you drive, the process of making this a cooler car by adding accessories is called Demomifying or the demomification phase which may last about 3 months to a year max.

UNDEMOMIFIED: "hey dude, look at that guy and his car, he looks like he should be driving a sex machine automobile, or at least something cooler than that, he should demomify his car, instead he's driving a mom car? Smh.
DEMOMIFIED: Hey dude, look at that guy and his car, that car looks sick, its totally not a mom car or anything. all the accessories make it look cooler and more badass than it actually is. i respect this kid
