look up any word, like sex:
 
1.
A social situation in which one wanders into an inescapable -and typically brutally awkward - conversation unwittingly. Often victims will step into the conversation bear trap with an innocuous greeting like, "Hey Deb, what's up?"
"Careful around that new Account Manager, dude's a conversation bear trap."

"Whatever you do, don't ask Andi about her wedding. Conversation bear trap."
