Kárikázó is a traditional Hungarian folk dance performed by women in 4/4 time to a capella rather than music.
Kárikázós were usually performed during weddings or other communal occasions and involved women forming a ring or circle by either holding hands or wrapping their arms around each other's waists.
The themes within the songs the girls/women sing revolve around attraction, courtship, love, or heartbreak.
The best lyric I have encountered thus far: "When he takes your hand in his, a hundred devils fill his heart".
