Among some the term beaver is suggestive, or even offensive. Think Thelma & Louise; "Damn! I hate that! I hate being called a beaver! Don't you?"

It's a particularly lowbrow bit of slang and not something that worried me when I recently mentioned the name dbeaver in a professional context, although I am aware of it. It pleases me that I spend my time among people that are either ignorant of this matter or are happy to pretend they are.
