Life / (Kosi kosi łapci) - Polish folk song my grandmother sung to me [3]

Would anyone know of a Polish Folk song my grandmother sung to me. I only know the words phonetically, so it is way off. I was told it's about: boy meets girl, boy likes girl, boy loses girl. "Kutski, kutski vapski, boya neda vapski, vapska neta beta." If anyone thinks they may have a clue to what the song is, please let me know. I remember this song, but the I never know the correct words, and my dear grandmother passed many years ago.

Thank you,

Laura B.
