Technically, this word isn't really vulgar. It does however fall into the category of words you don't normally use in everyday conversation, so I think that makes it a good topic for this blog.
Let's face it, there are times we when all want to "tener relaciones sexuales" or "hacer el amor". And normally we take our time with these things.
But sometimes we gotta rush things, for one reason or another, and that's where "rapidín" comes in.
Nos echamos un rapidín
We had a quickie
You can also "tener un rapidín", you can tell your pareja (partner) "quiero un rapidín".
I think you get the picture, so enjoy your expanded vocabulary and have fun. And remember to "practica sexo seguro".
¡Hasta la próxima!
