In Hindi, many times the expression "thook ke chaaTnaa" is used to mean the English "to eat one's words" "KyoN bhaiyyaa bade chauRe ho ke keh rahe they kii is baar pass ho jaaoge? Phir tapak (fail) gaye! Koii baat nahiiN, hameN pataa hai thook ke chaaTnaa aapkii puraani aadat hai! Is there a similar expression in Urdu? How would this meaning be conveyed in Urdu among friends? Thanks!
