kakshmu - A Russian swear word that means you're so bad, even your dog

A Russian swear word that means you're so bad, even your dog is ashamed of you.

'Kakshmu!' my dad yelled when I failed my math test and ate my homework.

I got called 'kakshmu' after I tried to cook and burned everything.

She said 'kakshmu' when I tried to dance and looked like a flamingo in a hurricane.
