Now (b) noting that the word dongle sounds like dong is not a sexual joke. it is a joke, many would say in poor taste, but it isn't sexual in anyway unless your understanding of sexuality didn't evolve beyond age 12 and you still laugh every time the guy at the hot dog stand says wiener.

However, there is no denying that what she did was a gross abuse of whatever influence she had and was little more than playground pettiness on her part. They said something that was not in her taste and rather than be an adult and point out to them or to pycon that she was uncomfortable, she decided to publicly shame him. that's just the truth of the matter.
