1. yeah, sure, whatever. used normally by lazy teenagers who don't really like to listen to annoying parents.
2. yodeling stops walruses, in the case of ignorant teenage boys.
1. Mom: once you're done with the laundry, empty the dishwasher. and don't forget to take out the trash!

Child: ysw, now can I go back to my music?
2. girl: do you know what ysw means?
boy: uhh, I'm not sure, uhh, yodeling stops walruses?
