My mom has never called my dad by his nickname...she's always called him "Richard". His siblings still use his nickname and think it's funny that my mom never does. (I dont like the nickname either, but luckily I just have to call him "dad")

For me, I use "girl stuff" when referring to certain things that only girls get. The accessories that you use during "girl stuff" is just "stuff". Underwear is either "underwear" or "panties". Sex is "sex", not some annoyingly crude term. Certain body parts that guys have dont really get mentioned unless I'm using my dad's nickname as a slang term for when my boyfriend is being a jerk.
