A man just stopped me to ask if I’m a car mechanic. My first thought was “oh no does he need jumper cables?”. Then I realized it’s because I’m wearing my coveralls. I said, “No, these are my eatin’ pants, can’t fit in my skinny jeans no more”. He laughs without detecting any sarcasm. I’m pretty sure this is the same guy that wants you to name three songs of the band shirt you’re wearing, from the concert you went to, but as a girl you clearly couldn’t have loved. Just another day being a woman justifying your existence. #mansplaining #nofilter
So in other words she was dressed in coveralls, a guy made a joke based on that then laughed at her joke reply. Then ???, proving he clearly is a horrible sexist.
he might have just thought that "These are my eating pants" is a good joke. I would have laughed too. I puzzled what is so bad about laughing at a joke...
