I have never encountered this in 23 years of participating in open source projects of all kinds. 20 years back (in Debian) there was some banter on the mailing lists, but never of that nature. It was mainly jokes about women. The community was primarily of young males, and that did stop as more women got involved. However, I should state for completeness that none of it was anything that anyone should have been banned over; sometimes a joke was just a joke, before humour was effectively outlawed lest anyone get even slightly offended.
