Momstep 

A shit version of dupstep or trap that’s so watered down, even white, stay-at-home moms can listen to it. Usually it is the only form of electronic music you can find on the radio, mainly because a mom can’t figure out what SoundCloud is.

I hate getting rides from Jake because his mom, Shannon, is always playing momstep.
