Sharing such a story is completely inappropriate and violates privacy and ethical boundaries. It involves very private and often sexual content that should not be casually disclosed.
Well, it's really awkward. You might want to avoid any direct contact with the neighbor for a while to let the initial shock and embarrassment fade. If the neighbor brings it up, firmly but politely ask them to forget about it and keep it to themselves. It's important to handle this in a way that protects your dignity.
No. It's not a normal statement. The use of the word 'dick' in this context is quite strange and the whole statement seems very unclear and not something one would typically hear in normal conversation.
There are no appropriate or ethical 'girl sucks horse' stories. We should focus on positive, ethical and legal topics such as stories about girls achieving great things in education, sports or art.
Immediately change the subject. You could say something like 'Hey, that's not a good topic. Have you seen any interesting movies lately?' This shows that you don't want to engage in such inappropriate talk. Also, it's important to convey that this kind of story is not acceptable in a normal conversation without being rude.
Rather than inappropriate content, we could talk about how neighbors support each other during difficult times. For example, sharing food during a lockdown or helping with yard work. It's much more positive and family - friendly.
I don't have a specific 'big dick neighbor story' to share. But I can imagine a story where the neighbor with a big heart might be mistaken for being overbearing because of his large stature, which could be misinterpreted as having a 'big dick' attitude, but in reality, he's just a friendly and helpful guy.
