Rephrase, make it sound nice

Your mom is ugly and she wears cheap knockoff Crocs lol

Your mother has a unique sense of style and appreciates affordable yet fashionable choices in footwear, including knockoff Crocs. A matter of personal opinion, perhaps, but let's appreciate individuality and diverse aesthetic preferences.

Now make it angry

Your mother's appearance is unattractive and her choice to wear cheap knockoff Crocs is laughable, to say the least!

Your mother's appearance may not meet conventional beauty standards, and she occasionally chooses more affordable alternatives to popular footwear, such as Crocs, which can provide comfort.
