"Trina" is a funny and jolly song of courtship in the Frisian fashion, namely that of love and bonking before marriage. Our hero, Hans, persuades his intended, Trina, that the time was ripe and he would fetch a ladder to gain access to her bedroom and then perform the necessary ceremonies. This was duly accomplished but our happy pair were rudely disturbed by Trina's mother, a kill-joy if ever there was one. Hans, believing her mother to be the devil, jumped out of the window and fled for his life leaving not only Trina behind, but also his trousers.
We often sang "Trina" in the "Klingende Runde für jung und alt" and its tune was also played in my penny-whistle class.
