hainess
A person who's friendly, but also a little bit crazy. They'll help you if you're in trouble, but they'll also talk about their pet raccoon like it's the president.
'I'll save you from the math test if you let me feed my raccoon first.'
'I heard you got detention. Want me to take you to the park instead?'
'Don't worry about your problems. I've got a raccoon to worry about.'
