During the last game I had, my opponent and I coined a new phrase. It's somewhat of a homage to Paul Heaver and not meant to be derogative in any way.
We had both watched the video of his 2014 title match with Morgan Reid, and at 41:20 in, he tries a 4-straight manoeuvre in the midst of an asteroid field. When he placed the Falcon, there was maybe a millimetre to spare. Gasps and cheers from the assembled crowd. This isn't the first time we'd seen his remarkable skills in estimating exactly where a manoeuvre was going to end. In the 2013 title match, he did something similar, with the same sort of margin.
We had a situation come up in our game, and when a ship was manoeuvred with about a millimetre to spare, I announced "I've just done a Heaver!" and the term stuck for the rest of the game. When either of us pulled a manoeuvre that was within millimetres of an asteroid or another ship, we'd just done another Heaver.
Has anyone else got any colloquial terms for some manoeuvres or game elements that they find themselves using now?
