I call my mom Mama Lady, Mommy, Mommykins, Momo, Mother Dearest, and Mom. I call my step dad by his first name. When referring to them as grandparents I call my mom Grammy or Gramma, and my step dad Grumpy.
Lol. When my mother uses my first and middle name - Angela Mae - I hate them both- I retort with Iron Maiden, or Lois Anne..
But I usually get whacked on the side of the head if I call meh rents by their first names. xD I was bored one day and I adressed everyone as "Mr. ----" or "Mrs. ----" even when I didn't know their last name. xDD
Mom is Mom and Dad is Dad. I used to call them Mommy and Daddy, but now I really only do it when I'm sucking up. xDD
Me and a friend were waiting for my mom, and she meant to say "Where is your mommykins or daddykins?" and it came out "Where's your mommydad- er..." And we cracked up laughing. xD
