Haasblaas
A fancy way to say 'your poops' that makes you sound like you're trying to be a big shot but you're just mad.
At the beach, my dad said, 'Haasblaas!' because my brother took his towel.
During a game, my sister said, 'Haasblaas!' because I won again.
At the mall, my friend said, 'Haasblaas!' because I took her favorite shirt.
