You guys have seriously never heard someone call their mother "moms"?
Have you also never heard Grandma referred to as "grams"? Grandpa called "gramps"? Father called "pops"?
Same as those but maybe less common
Exactly that. "Moms" is less popular than "Pops", but it's definitely said by some people... >_>
