That would be in the same category as giving someone a coffee mug with the words "Guess how many donuts I can fit on my d..k". Might have been funny to the gift giver but perhaps giving these types of gifts to a Sexual Harassment Referral Officer is not the wisest thing to do. Probably fortunate in one way that it was a secret Santa gift so it couldn't be traced.
Word of caution - think carefully about the gift, about the person for whom the gift is intended and whether or not they or any other person who may see the gift will be offended etc.
