Get the asshole mom mug.a girl's buttocks that sags with wrinkles near the thigh area but yet is flatter than a homeless woman's chest on crack. This is usually obtained by a woman sitting in an office chair all day, every day.
"dang! I like that chick is hot but she got a momass! grooooooss!"
"yo look at that momass, I bet you could use that as a cutting board!"
"hey, your mom's ass looks like shes been sitting on the driveway for the past 10 years"
