A portmanteau formed by combining 'chudaap' and 'shit'. It is a cooler version of the relatively uncool 'chudaap', which is also used by chai wallas,rickshaw wallas in Orissa,Maharasthra and UP thus making it a little crude. The shit added at the end gives chudaap a black US rap star twist hence making it socially acceptable and increasing your chances of getting laid.
Person Bi: " STOP THIS CHUDAAPSHIT!"
Person A: :X
