Throwing a Track

When you are talking in or in front of a group of people and you make a good point, but either nobody was listening until then or they don't understand.

Context:
When a tank throws a track, it takes a long time to repair. It is also very annoying and happens relatively easily. In a conversation, throwing a track can take a while to recover from.

Keeping calm before going on stage can help keep you from throwing a track.
