man, do you have a round bum!

j was pulling up her pants and n was sitting on the toilet... looking at her sister... and says 'man, do you have a round bum!'...

j looks really hurt and says 'that's not a nice thing to say!' and n goes 'why?? it's a very nice bum!'

n gets off the toilet, tries to check out her own bum for roundness, and makes several circles trying to see the entire thing...
