Used exclusively for females, often seen as demeaning or objectifying. The boss was reprimanded for referring to female staff as 'totty'.
Pro Tip 2/3
Very Informal
Extremely casual and might be offensive in a formal or professional setting. I was uncomfortable when he casually mentioned 'office totty' during the meeting.
Pro Tip 3/3
British Slang
It's a British term not widely used or understood outside the UK. When I mentioned 'totty' abroad, people were confused.
