Mom Phone
A big chunky cell phone that would normally be used by a mom, but is being used by a high school-age kid. This phone is NOT, under any circumstances, to be called a Mom Phone when an adult female is using it.
Jerry: Hey Victor, can I use your Mom Phone?
Victor: Yes indeed!
Victor: Yes indeed!
Stay-at-Phone Mom
A woman with kids who decides not to work, so that she can spend more quality time with her cell phone. Often spotted at Costco, pushing strollers, and supervising playground visits while yakking to other S-A-P moms on her phone.
Wow, look at that Stay-At-Phone mom over there by the swingset! I bet her kids are crying because she's too busy talking to her best friend and won't push them.
