Other forms: buttinskys
A buttinsky is that one person who just can’t resist jumping into everyone else's business, offering advice or opinions even when no one asks for it.
The word buttinsky is a fun mix of butt, as in when someone "butts in," and the playful suffix -insky. It brings to mind that nosy neighbor or friend who always has to chime in on every situation, even when it’s not really their business. It’s a lighthearted way to call out those folks who often end up being more annoying than helpful, regardless of their good intentions.
