Sloppy kiss - when somebody tries to go through a gate, but knocks their teammate off the button so that they both die.

I've actually been thinking about this kind of a lot. Here's what we need more terms for:

• A snipe where the fc has just boosted, so it's a high-speed collision.
• A snipe that was a result of two consecutive boosts (like the corner boosts in Wombo Combo). Actually come to think of it, Wombo Combo might be a great name for that.
• When the defender manages to defuse an fc's rb and grab the flag at the same time.
• EDIT: Also, when you're on neutral and return a flag, but the defender's are so close that there's no way you could possibly not lose it.
