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.

Trombo is a combination of any three things. It is a marriage of the words "Tri" and "combo".
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"
