Why are you trippin' cuz...lol

so my cousin calls me earlier today upset because him and his girl where in some store. He saw another brotha wearing some tight sneakers and he told his girl because he hadnt seen sneakers like that before. Well she ask him....why dont you ask him where he got it and he of course replied that men cant do like women do and just walk up to a dude he doesnt know and ask such a question. So as they are leaving the store....she stops and ask the guy and my cousin keeps walking. Now my cousin is upset....because he thought the guy was trying to hit on her because he kept trying to keep the conversation going after answering the initial question
