My first thought was, "Well, was he making you uncomfortable and creating a hostile work environment for you? If so, then yes."
I was unsatisfied with that answer, though, because it is too black-and-white for me. To my mind, the situation is a bit more nuanced. Was she harassed? By the technical definition of the term, I think that she was.
By her own admission, she laughed at his joke the first time even though she did not find it funny. To a nervous new hire who is trying to fit in, this could be taken as a sign of approval. She never told him that his jokes made her uncomfortable, but at the same time, one might argue that she should not have to. Was it harassment? I guess if we want to set the bar really, really low then it was. I am a little old-school though, and I have always felt that there should be thresholds to these things.
Harassment through innocent ignorance is far less egregious in my opinion than harassment that crosses boundaries that anyone with a normal sense of social moors should understand is over the line. In the latter case, I am talking about things along the lines of overt advances, lewd comments directed at the target, inappropriate touching - things that any rational person should understand is unacceptable in a workplace. In the former case though, most people might find puerile meat jokes unfunny, or even a bit tiresome after awhile, but most would not find them a source of tension and discomfort.
At some point I think the onus is on us to let others around us know where our personal boundaries reside. If somebody's behaviour in the workplace bothers you; tell them. Most people are reasonable, and will respect your threshold of comfort. If they do not, then it becomes a wilful act, and is unquestionably harassment in my mind.
