Botellón: Can this word also mean "money box/jar", "piggy-bank".

Question

From my dictionary and this site the definition is:
Botellón: informal street gathering where young people meet to drink and socialize.

Here is some context.
1.) Cada vez que gano dinero, guardo la mitad en el botellón.
2.) Hace falta mucho tiempo para llenar un botellón tan grande.
3.) Pero todas las noches, una por una, las relucientes monedas acaban en le botellón.

I am very familiar with "alcancía" in this context.

Answer 1

The big plastic bottles of water that are found in offices (turned upside down in a dispensing machine) are called botellones, and that seems to be the meaning here. Of course, the speaker could be referring to any oversized bottle.

1. Every time I make some money, I save half in the jug.
2. It's going to take a long time to fill a jug that big.
3. But every night, one by one, the shiny coins end up in the jug.

Answer 2

Botellón is, morphologically, botella + -ón, a suffix that indicates something big, bad, violent, and other things. I could easily be a big bottle to be used as a money box. In Spain, in general, the word is used as indicated in your dictionary.
