1.) The aggregates of solid leftover when milk-cream is boiled to get ghee (butter), that looks like waste but is edible
2.) a local homemade dish in India that is made from kachra and sugar, which is of a very high calorific value
"Yay! Mom is making butter out of cream, so we will get some kachra."
"It's been a long time we've had some sweet Kachra."
The epitome of cheapness and chamakness. Simply unprincipled and immoral with extremely low standards.
Ewwww butti ! You’re so kachra !
