Though they share many of the same characteristics, it is important not to confuse your mom with yo momma.
Yo momma typically possesses a wide range of undesirable traits-including but not limited to: unattractiveness, obesity, low intelligence, poverty, poor bodily/oral hygiene, promiscuity, unappealing odor, hirsuteness, lackluster work ethic-and exhibits these traits to a degree that observers may find shocking or humorous. Generally, these qualities emerge via some linguistic misunderstanding or the employment of some device in a manner for which it was not originally intended, viz: due to yo momma’s unhealthy corpulence, she requires the substitution of a microwave oven in place of a pager, presumably because her engorged fingers would be unable to operate the small buttons found on a typical pager (though it is unclear how exactly a microwave would serve as a viable alternative, as this appliance is in no way designed to serve a similar function) . In most cases, yo momma is either unaware of or unconcerned with how others perceive her, contributing to the scorn heaped on yo momma by those who disapprove of her lifestyle choices.
Your mom, by comparison, tends to be much more directly demonstrative of her seemingly negative traits, and may frequently even embrace her shortcomings, of which promiscuity is by far the most dominant. In fact, despite any other potentially unappealing traits, your mom’s well-known licentious ways and cheerful agreeableness to try anything twice have greatly boosted her popularity within the community. In some cases, your mom goes so far as to take pride in her sexual uninhibitedness with strangers, as well as with your close friends and acquaintances, as evidenced by their extensive knowledge of what “she said,” or what she “did last night.”
