"Im eating chicken and rice sob"
"She dont want me man chicken and rice"
"I bet you eat chicken and rice"
"Fuck man time for chicken and rice"

(куром насмех in Russian): when you do something so silly/stupid- but never retargerous- that even a chicken at the local farm will make laughing stock put of you
