κουμπάροςkoom-BAH-ross[kumˈbaros]
the wedding sponsor, often godparent to the first child — the best man
Closest in English: best-man, bestman, sponsor. None of them covers it.
At an Orthodox wedding the koumbaros swaps the two crowns over the couple's heads three times, and by custom often baptises their first child too. The bond counts as family for life. English has the best man, whose duties end with the speech.
