Someone who you don't actually like, but you hang around because you feel bad for them and/or you don't want to hurt their feelings. It's likely that a
pity friend will end up either
bugging you constantly or hardly ever speaking to you. Having a pity friend technically counts as being a fake friend, however it is somewhat different in that, unless you're really an asshole, you'll likely end up trying not to do anything to purposefully hurt them. Pity friendships are usually established in an attempt to be nice to the friend. However, it's not a healthy friendship to stay in for long, and you should end as quickly as possible, especially if the friend ends up
a burden on you.
