I can't see that mary's post is rude. The thrust of it is positive and a lazy term (that is debatably offensive), doesn't change
the context much IMO.
As someone who has a history/reputation for rudeness I would like to register my concern.
My quals to comment on said subject = Master of Rudeness with associate Diploma in Lavatory Humour. (Sydney Univ.)

Rudeness is generally considered less to be about the words used and more about the context the words are used in. In this example mary makes it clear she would love to meet and party with them - that is hardly derogatory. With this in mind, to me it softens the descriptors significantly.

I think if we are talking rude, we could consider jumping all over a first time poster not the friendliest , most encouraging welcome to the board either.
