"A fling" - a short, casual romance.

Thank you both! ;)

You might like to know that to fling usually means to toss easily or carelessly. And so there is a feeling of throw away love, temporary love.

Fling = adventure of love, playing love, other trouble love. In spanish we said sólo fue un "amor de centavo" or it was a "llamarada de petate" "comenzó y terminó en menos de lo que canta un gallo" jejeje
