A scorched earth approach to obliterating someone's conversation that is not your own.
Interrupting a conversation and quickly dominating the topic, or changing it entirely.

Much like Conversation Hijack, but with a militant approach.
Jody and I were having a private conversation when Carol walked in, asked us what we were talking about, and then quickly changed the topic to something she was interested in - Obliterating our conversation with Conversation Napalm.
