Wash Bottles (or washing bottles, bottle washer, etc) is simply a term used, either jokingly, seriously or somewhere in between, to describe the act of fellatio. Do note, however, that this phrase must be used with a STRONG Portuguese accent, as was common in the development of this catch-phrase. The phrase is often used to describe a negative situation, or towards someone in a negative way, similar to telling someone to fuck-off.
The words can be interchanged depending on the use and tense of the incident in which the phrase is being used - see below examples
"Hey buddy, go wash bottles!"
"Your mom is a bottle washer!"
"you washed bottles for a living"
and so on - take it and go!
