Girls perspective/advice needed :(

Whenever I talk to same age group 2X chromosome being (I am referring to 1st /2nd talk/meet). Whenever I talk some bullshit/funny/cute/rant/dark (as per their perspective) from my side I try to be funny. The response I get is: m Tera sar phod dungi/iss cheez se sar me marugi/maar khayega tu etc...(with a simple smile that I sometime find cute sometimes creepy) I will not mind you obviously but it happened quite often( with different friends) now that I am considering what it actually means considering I'm almost 6 feet 180 pound being (not literally they want to smash something over my head ) right ? Right 👀 I think they want to say tu chu*** , bhad*** etc or anything else please help this poor soul here
