The mother talking about how her son smells bad now he's reached puberty. Maybe it's for Tide laundry. I don't know, because the premise itself churns my stomach. So very icky. I don't want to know. No one needs to know. The kid is just sitting there doing homework, watching his mother whoop-whoop-fist-bump-shimmy-shake over his puberty and not fleeing in embarrassment, which is what a real kid would do.
Because that's just not gross enough (stop reading now if you are easily grossed out), that reminds me of Wendi McLendon-Covey's character in Bridesmaids talking about her pubescent sons being so disgusting and there being "semen everywhere!" ("I cracked a blanket in half!")
