In a billiards game a Trombo is a 3 ball combination resulting in a made shot. It is a combo word using the word triple and the word combo.
A person walks up to a pool table and hits the cue ball into the one ball which in turn hits the six ball which in turn sinks the seven ball. There you have it, a successful trombo.

All three of our daughters have birthdays in June. We have one large party to celebrate all of them at the same time. It is always called a "Trombo Party"
