Contra dance. Contra dance (also contradance, contra-dance and other variant spellings) is a folk dance made up of long lines of couples. It has mixed origins from English country dance, Scottish, French dance styles in the 17th century, with strong African influence from Appalachia.
Contra dance is a form of dance that thrusts a different person of the opposite sex into your arms every 30 seconds or so. Actually, this is only true sometimes. It might be more prudent, but less whimsical, to say that contra dance is one of the few dance forms where by the end of the evening you are likely to have danced with everyone.
