That speaks volumes.

I took this photo in Amsterdam red-light district, Holland. Seeing this photo, where'd the term red-light district come form is self-explanatory. Yep, the red lights. Generally speaking, those red lights are used as signs of erotic pleasure or something similar. Speaking of self-explanatory, one of my English acquaintances used a funny word to describe his recent club experience. A few weeks ago, he went to a club with his brother. The club required an entrance fee, so they paid it and then went inside. What they saw in the club was a little too different from they had expected. There were a bunch of guys, and only a few ladies. My acquaintance said that it was a sausage fest. That speaks volumes. Self-explanatory.
